Fix #142 : break long unbroken paste titles instead of forcing horizontal scroll

Add word-break: normal; overflow-wrap: anywhere to .paste-title-bar h1 so a >120-char unbroken title wraps inside the title card at mobile width instead of producing an internal + page-level horizontal scrollbar.
Merge pull request 'Wrap: break long words, no horizontal scroll while wrap enabled' (#155 ) from fix-152 into dev

                    GNU AFFERO GENERAL PUBLIC LICENSE
                       Version 3, 19 November 2007
 Copyright (C) 2007 Free Software Foundation, Inc. <https://fsf.org/>
 Everyone is permitted to copy and distribute verbatim copies
 of this license document, but changing it is not allowed.
                            Preamble
  The GNU Affero General Public License is a free, copyleft license for
 software and other kinds of works, specifically designed to ensure
 cooperation with the community in the case of network server software.
  The licenses for most software and other practical works are designed
 to take away your freedom to share and change the works.  By contrast,
 our General Public Licenses are intended to guarantee your freedom to
 share and change all versions of a program--to make sure it remains free
 software for all its users.
  When we speak of free software, we are referring to freedom, not
 price.  Our General Public Licenses are designed to make sure that you
 have the freedom to distribute copies of free software (and charge for
 them if you wish), that you receive source code or can get it if you
 want it, that you can change the software or use pieces of it in new
 free programs, and that you know you can do these things.
  Developers that use our General Public Licenses protect your rights
 with two steps: (1) assert copyright on the software, and (2) offer
 you this License which gives you legal permission to copy, distribute
 and/or modify the software.
  A secondary benefit of defending all users' freedom is that
 improvements made in alternate versions of the program, if they
 receive widespread use, become available for other developers to
 incorporate.  Many developers of free software are heartened and
 encouraged by the resulting cooperation.  However, in the case of
 software used on network servers, this result may fail to come about.
 The GNU General Public License permits making a modified version and
 letting the public access it on a server without ever releasing its
 source code to the public.
  The GNU Affero General Public License is designed specifically to
 ensure that, in such cases, the modified source code becomes available
 to the community.  It requires the operator of a network server to
 provide the source code of the modified version running there to the
 users of that server.  Therefore, public use of a modified version, on
 a publicly accessible server, gives the public access to the source
 code of the modified version.
  An older license, called the Affero General Public License and
 published by Affero, was designed to accomplish similar goals.  This is
 a different license, not a version of the Affero GPL, but Affero has
 released a new version of the Affero GPL which permits relicensing under
 this license.
  The precise terms and conditions for copying, distribution and
 modification follow.
                       TERMS AND CONDITIONS
  0. Definitions.
  "This License" refers to version 3 of the GNU Affero General Public License.
  "Copyright" also means copyright-like laws that apply to other kinds of
 works, such as semiconductor masks.
  "The Program" refers to any copyrightable work licensed under this
 License.  Each licensee is addressed as "you".  "Licensees" and
 "recipients" may be individuals or organizations.
  To "modify" a work means to copy from or adapt all or part of the work
 in a fashion requiring copyright permission, other than the making of an
 exact copy.  The resulting work is called a "modified version" of the
 earlier work or a work "based on" the earlier work.
  A "covered work" means either the unmodified Program or a work based
 on the Program.
  To "propagate" a work means to do anything with it that, without
 permission, would make you directly or secondarily liable for
 infringement under applicable copyright law, except executing it on a
 computer or modifying a private copy.  Propagation includes copying,
 distribution (with or without modification), making available to the
 public, and in some countries other activities as well.
  To "convey" a work means any kind of propagation that enables other
 parties to make or receive copies.  Mere interaction with a user through
 a computer network, with no transfer of a copy, is not conveying.
  An interactive user interface displays "Appropriate Legal Notices"
 to the extent that it includes a convenient and prominently visible
 feature that (1) displays an appropriate copyright notice, and (2)
 tells the user that there is no warranty for the work (except to the
 extent that warranties are provided), that licensees may convey the
 work under this License, and how to view a copy of this License.  If
 the interface presents a list of user commands or options, such as a
 menu, a prominent item in the list meets this criterion.
  1. Source Code.
  The "source code" for a work means the preferred form of the work
 for making modifications to it.  "Object code" means any non-source
 form of a work.
  A "Standard Interface" means an interface that either is an official
 standard defined by a recognized standards body, or, in the case of
 interfaces specified for a particular programming language, one that
 is widely used among developers working in that language.
  The "System Libraries" of an executable work include anything, other
 than the work as a whole, that (a) is included in the normal form of
 packaging a Major Component, but which is not part of that Major
 Component, and (b) serves only to enable use of the work with that
 Major Component, or to implement a Standard Interface for which an
 implementation is available to the public in source code form.  A
 "Major Component", in this context, means a major essential component
 (kernel, window system, and so on) of the specific operating system
 (if any) on which the executable work runs, or a compiler used to
 produce the work, or an object code interpreter used to run it.
  The "Corresponding Source" for a work in object code form means all
 the source code needed to generate, install, and (for an executable
 work) run the object code and to modify the work, including scripts to
 control those activities.  However, it does not include the work's
 System Libraries, or general-purpose tools or generally available free
 programs which are used unmodified in performing those activities but
 which are not part of the work.  For example, Corresponding Source
 includes interface definition files associated with source files for
 the work, and the source code for shared libraries and dynamically
 linked subprograms that the work is specifically designed to require,
 such as by intimate data communication or control flow between those
 subprograms and other parts of the work.
  The Corresponding Source need not include anything that users
 can regenerate automatically from other parts of the Corresponding
 Source.
  The Corresponding Source for a work in source code form is that
 same work.
  2. Basic Permissions.
  All rights granted under this License are granted for the term of
 copyright on the Program, and are irrevocable provided the stated
 conditions are met.  This License explicitly affirms your unlimited
 permission to run the unmodified Program.  The output from running a
 covered work is covered by this License only if the output, given its
 content, constitutes a covered work.  This License acknowledges your
 rights of fair use or other equivalent, as provided by copyright law.
  You may make, run and propagate covered works that you do not
 convey, without conditions so long as your license otherwise remains
 in force.  You may convey covered works to others for the sole purpose
 of having them make modifications exclusively for you, or provide you
 with facilities for running those works, provided that you comply with
 the terms of this License in conveying all material for which you do
 not control copyright.  Those thus making or running the covered works
 for you must do so exclusively on your behalf, under your direction
 and control, on terms that prohibit them from making any copies of
 your copyrighted material outside their relationship with you.
  Conveying under any other circumstances is permitted solely under
 the conditions stated below.  Sublicensing is not allowed; section 10
 makes it unnecessary.
  3. Protecting Users' Legal Rights From Anti-Circumvention Law.
  No covered work shall be deemed part of an effective technological
 measure under any applicable law fulfilling obligations under article
 11 of the WIPO copyright treaty adopted on 20 December 1996, or
 similar laws prohibiting or restricting circumvention of such
 measures.
  When you convey a covered work, you waive any legal power to forbid
 circumvention of technological measures to the extent such circumvention
 is effected by exercising rights under this License with respect to
 the covered work, and you disclaim any intention to limit operation or
 modification of the work as a means of enforcing, against the work's
 users, your or third parties' legal rights to forbid circumvention of
 technological measures.
  4. Conveying Verbatim Copies.
  You may convey verbatim copies of the Program's source code as you
 receive it, in any medium, provided that you conspicuously and
 appropriately publish on each copy an appropriate copyright notice;
 keep intact all notices stating that this License and any
 non-permissive terms added in accord with section 7 apply to the code;
 keep intact all notices of the absence of any warranty; and give all
 recipients a copy of this License along with the Program.
  You may charge any price or no price for each copy that you convey,
 and you may offer support or warranty protection for a fee.
  5. Conveying Modified Source Versions.
  You may convey a work based on the Program, or the modifications to
 produce it from the Program, in the form of source code under the
 terms of section 4, provided that you also meet all of these conditions:
    a) The work must carry prominent notices stating that you modified
    it, and giving a relevant date.
    b) The work must carry prominent notices stating that it is
    released under this License and any conditions added under section
    7.  This requirement modifies the requirement in section 4 to
    "keep intact all notices".
    c) You must license the entire work, as a whole, under this
    License to anyone who comes into possession of a copy.  This
    License will therefore apply, along with any applicable section 7
    additional terms, to the whole of the work, and all its parts,
    regardless of how they are packaged.  This License gives no
    permission to license the work in any other way, but it does not
    invalidate such permission if you have separately received it.
    d) If the work has interactive user interfaces, each must display
    Appropriate Legal Notices; however, if the Program has interactive
    interfaces that do not display Appropriate Legal Notices, your
    work need not make them do so.
  A compilation of a covered work with other separate and independent
 works, which are not by their nature extensions of the covered work,
 and which are not combined with it such as to form a larger program,
 in or on a volume of a storage or distribution medium, is called an
 "aggregate" if the compilation and its resulting copyright are not
 used to limit the access or legal rights of the compilation's users
 beyond what the individual works permit.  Inclusion of a covered work
 in an aggregate does not cause this License to apply to the other
 parts of the aggregate.
  6. Conveying Non-Source Forms.
  You may convey a covered work in object code form under the terms
 of sections 4 and 5, provided that you also convey the
 machine-readable Corresponding Source under the terms of this License,
 in one of these ways:
    a) Convey the object code in, or embodied in, a physical product
    (including a physical distribution medium), accompanied by the
    Corresponding Source fixed on a durable physical medium
    customarily used for software interchange.
    b) Convey the object code in, or embodied in, a physical product
    (including a physical distribution medium), accompanied by a
    written offer, valid for at least three years and valid for as
    long as you offer spare parts or customer support for that product
    model, to give anyone who possesses the object code either (1) a
    copy of the Corresponding Source for all the software in the
    product that is covered by this License, on a durable physical
    medium customarily used for software interchange, for a price no
    more than your reasonable cost of physically performing this
    conveying of source, or (2) access to copy the
    Corresponding Source from a network server at no charge.
    c) Convey individual copies of the object code with a copy of the
    written offer to provide the Corresponding Source.  This
    alternative is allowed only occasionally and noncommercially, and
    only if you received the object code with such an offer, in accord
    with subsection 6b.
    d) Convey the object code by offering access from a designated
    place (gratis or for a charge), and offer equivalent access to the
    Corresponding Source in the same way through the same place at no
    further charge.  You need not require recipients to copy the
    Corresponding Source along with the object code.  If the place to
    copy the object code is a network server, the Corresponding Source
    may be on a different server (operated by you or a third party)
    that supports equivalent copying facilities, provided you maintain
    clear directions next to the object code saying where to find the
    Corresponding Source.  Regardless of what server hosts the
    Corresponding Source, you remain obligated to ensure that it is
    available for as long as needed to satisfy these requirements.
    e) Convey the object code using peer-to-peer transmission, provided
    you inform other peers where the object code and Corresponding
    Source of the work are being offered to the general public at no
    charge under subsection 6d.
  A separable portion of the object code, whose source code is excluded
 from the Corresponding Source as a System Library, need not be
 included in conveying the object code work.
  A "User Product" is either (1) a "consumer product", which means any
 tangible personal property which is normally used for personal, family,
 or household purposes, or (2) anything designed or sold for incorporation
 into a dwelling.  In determining whether a product is a consumer product,
 doubtful cases shall be resolved in favor of coverage.  For a particular
 product received by a particular user, "normally used" refers to a
 typical or common use of that class of product, regardless of the status
 of the particular user or of the way in which the particular user
 actually uses, or expects or is expected to use, the product.  A product
 is a consumer product regardless of whether the product has substantial
 commercial, industrial or non-consumer uses, unless such uses represent
 the only significant mode of use of the product.
  "Installation Information" for a User Product means any methods,
 procedures, authorization keys, or other information required to install
 and execute modified versions of a covered work in that User Product from
 a modified version of its Corresponding Source.  The information must
 suffice to ensure that the continued functioning of the modified object
 code is in no case prevented or interfered with solely because
 modification has been made.
  If you convey an object code work under this section in, or with, or
 specifically for use in, a User Product, and the conveying occurs as
 part of a transaction in which the right of possession and use of the
 User Product is transferred to the recipient in perpetuity or for a
 fixed term (regardless of how the transaction is characterized), the
 Corresponding Source conveyed under this section must be accompanied
 by the Installation Information.  But this requirement does not apply
 if neither you nor any third party retains the ability to install
 modified object code on the User Product (for example, the work has
 been installed in ROM).
  The requirement to provide Installation Information does not include a
 requirement to continue to provide support service, warranty, or updates
 for a work that has been modified or installed by the recipient, or for
 the User Product in which it has been modified or installed.  Access to a
 network may be denied when the modification itself materially and
 adversely affects the operation of the network or violates the rules and
 protocols for communication across the network.
  Corresponding Source conveyed, and Installation Information provided,
 in accord with this section must be in a format that is publicly
 documented (and with an implementation available to the public in
 source code form), and must require no special password or key for
 unpacking, reading or copying.
  7. Additional Terms.
  "Additional permissions" are terms that supplement the terms of this
 License by making exceptions from one or more of its conditions.
 Additional permissions that are applicable to the entire Program shall
 be treated as though they were included in this License, to the extent
 that they are valid under applicable law.  If additional permissions
 apply only to part of the Program, that part may be used separately
 under those permissions, but the entire Program remains governed by
 this License without regard to the additional permissions.
  When you convey a copy of a covered work, you may at your option
 remove any additional permissions from that copy, or from any part of
 it.  (Additional permissions may be written to require their own
 removal in certain cases when you modify the work.)  You may place
 additional permissions on material, added by you to a covered work,
 for which you have or can give appropriate copyright permission.
  Notwithstanding any other provision of this License, for material you
 add to a covered work, you may (if authorized by the copyright holders of
 that material) supplement the terms of this License with terms:
    a) Disclaiming warranty or limiting liability differently from the
    terms of sections 15 and 16 of this License; or
    b) Requiring preservation of specified reasonable legal notices or
    author attributions in that material or in the Appropriate Legal
    Notices displayed by works containing it; or
    c) Prohibiting misrepresentation of the origin of that material, or
    requiring that modified versions of such material be marked in
    reasonable ways as different from the original version; or
    d) Limiting the use for publicity purposes of names of licensors or
    authors of the material; or
    e) Declining to grant rights under trademark law for use of some
    trade names, trademarks, or service marks; or
    f) Requiring indemnification of licensors and authors of that
    material by anyone who conveys the material (or modified versions of
    it) with contractual assumptions of liability to the recipient, for
    any liability that these contractual assumptions directly impose on
    those licensors and authors.
  All other non-permissive additional terms are considered "further
 restrictions" within the meaning of section 10.  If the Program as you
 received it, or any part of it, contains a notice stating that it is
 governed by this License along with a term that is a further
 restriction, you may remove that term.  If a license document contains
 a further restriction but permits relicensing or conveying under this
 License, you may add to a covered work material governed by the terms
 of that license document, provided that the further restriction does
 not survive such relicensing or conveying.
  If you add terms to a covered work in accord with this section, you
 must place, in the relevant source files, a statement of the
 additional terms that apply to those files, or a notice indicating
 where to find the applicable terms.
  Additional terms, permissive or non-permissive, may be stated in the
 form of a separately written license, or stated as exceptions;
 the above requirements apply either way.
  8. Termination.
  You may not propagate or modify a covered work except as expressly
 provided under this License.  Any attempt otherwise to propagate or
 modify it is void, and will automatically terminate your rights under
 this License (including any patent licenses granted under the third
 paragraph of section 11).
  However, if you cease all violation of this License, then your
 license from a particular copyright holder is reinstated (a)
 provisionally, unless and until the copyright holder explicitly and
 finally terminates your license, and (b) permanently, if the copyright
 holder fails to notify you of the violation by some reasonable means
 prior to 60 days after the cessation.
  Moreover, your license from a particular copyright holder is
 reinstated permanently if the copyright holder notifies you of the
 violation by some reasonable means, this is the first time you have
 received notice of violation of this License (for any work) from that
 copyright holder, and you cure the violation prior to 30 days after
 your receipt of the notice.
  Termination of your rights under this section does not terminate the
 licenses of parties who have received copies or rights from you under
 this License.  If your rights have been terminated and not permanently
 reinstated, you do not qualify to receive new licenses for the same
 material under section 10.
  9. Acceptance Not Required for Having Copies.
  You are not required to accept this License in order to receive or
 run a copy of the Program.  Ancillary propagation of a covered work
 occurring solely as a consequence of using peer-to-peer transmission
 to receive a copy likewise does not require acceptance.  However,
 nothing other than this License grants you permission to propagate or
 modify any covered work.  These actions infringe copyright if you do
 not accept this License.  Therefore, by modifying or propagating a
 covered work, you indicate your acceptance of this License to do so.
  10. Automatic Licensing of Downstream Recipients.
  Each time you convey a covered work, the recipient automatically
 receives a license from the original licensors, to run, modify and
 propagate that work, subject to this License.  You are not responsible
 for enforcing compliance by third parties with this License.
  An "entity transaction" is a transaction transferring control of an
 organization, or substantially all assets of one, or subdividing an
 organization, or merging organizations.  If propagation of a covered
 work results from an entity transaction, each party to that
 transaction who receives a copy of the work also receives whatever
 licenses to the work the party's predecessor in interest had or could
 give under the previous paragraph, plus a right to possession of the
 Corresponding Source of the work from the predecessor in interest, if
 the predecessor has it or can get it with reasonable efforts.
  You may not impose any further restrictions on the exercise of the
 rights granted or affirmed under this License.  For example, you may
 not impose a license fee, royalty, or other charge for exercise of
 rights granted under this License, and you may not initiate litigation
 (including a cross-claim or counterclaim in a lawsuit) alleging that
 any patent claim is infringed by making, using, selling, offering for
 sale, or importing the Program or any portion of it.
  11. Patents.
  A "contributor" is a copyright holder who authorizes use under this
 License of the Program or a work on which the Program is based.  The
 work thus licensed is called the contributor's "contributor version".
  A contributor's "essential patent claims" are all patent claims
 owned or controlled by the contributor, whether already acquired or
 hereafter acquired, that would be infringed by some manner, permitted
 by this License, of making, using, or selling its contributor version,
 but do not include claims that would be infringed only as a
 consequence of further modification of the contributor version.  For
 purposes of this definition, "control" includes the right to grant
 patent sublicenses in a manner consistent with the requirements of
 this License.
  Each contributor grants you a non-exclusive, worldwide, royalty-free
 patent license under the contributor's essential patent claims, to
 make, use, sell, offer for sale, import and otherwise run, modify and
 propagate the contents of its contributor version.
  In the following three paragraphs, a "patent license" is any express
 agreement or commitment, however denominated, not to enforce a patent
 (such as an express permission to practice a patent or covenant not to
 sue for patent infringement).  To "grant" such a patent license to a
 party means to make such an agreement or commitment not to enforce a
 patent against the party.
  If you convey a covered work, knowingly relying on a patent license,
 and the Corresponding Source of the work is not available for anyone
 to copy, free of charge and under the terms of this License, through a
 publicly available network server or other readily accessible means,
 then you must either (1) cause the Corresponding Source to be so
 available, or (2) arrange to deprive yourself of the benefit of the
 patent license for this particular work, or (3) arrange, in a manner
 consistent with the requirements of this License, to extend the patent
 license to downstream recipients.  "Knowingly relying" means you have
 actual knowledge that, but for the patent license, your conveying the
 covered work in a country, or your recipient's use of the covered work
 in a country, would infringe one or more identifiable patents in that
 country that you have reason to believe are valid.
  If, pursuant to or in connection with a single transaction or
 arrangement, you convey, or propagate by procuring conveyance of, a
 covered work, and grant a patent license to some of the parties
 receiving the covered work authorizing them to use, propagate, modify
 or convey a specific copy of the covered work, then the patent license
 you grant is automatically extended to all recipients of the covered
 work and works based on it.
  A patent license is "discriminatory" if it does not include within
 the scope of its coverage, prohibits the exercise of, or is
 conditioned on the non-exercise of one or more of the rights that are
 specifically granted under this License.  You may not convey a covered
 work if you are a party to an arrangement with a third party that is
 in the business of distributing software, under which you make payment
 to the third party based on the extent of your activity of conveying
 the work, and under which the third party grants, to any of the
 parties who would receive the covered work from you, a discriminatory
 patent license (a) in connection with copies of the covered work
 conveyed by you (or copies made from those copies), or (b) primarily
 for and in connection with specific products or compilations that
 contain the covered work, unless you entered into that arrangement,
 or that patent license was granted, prior to 28 March 2007.
  Nothing in this License shall be construed as excluding or limiting
 any implied license or other defenses to infringement that may
 otherwise be available to you under applicable patent law.
  12. No Surrender of Others' Freedom.
  If conditions are imposed on you (whether by court order, agreement or
 otherwise) that contradict the conditions of this License, they do not
 excuse you from the conditions of this License.  If you cannot convey a
 covered work so as to satisfy simultaneously your obligations under this
 License and any other pertinent obligations, then as a consequence you may
 not convey it at all.  For example, if you agree to terms that obligate you
 to collect a royalty for further conveying from those to whom you convey
 the Program, the only way you could satisfy both those terms and this
 License would be to refrain entirely from conveying the Program.
  13. Remote Network Interaction; Use with the GNU General Public License.
  Notwithstanding any other provision of this License, if you modify the
 Program, your modified version must prominently offer all users
 interacting with it remotely through a computer network (if your version
 supports such interaction) an opportunity to receive the Corresponding
 Source of your version by providing access to the Corresponding Source
 from a network server at no charge, through some standard or customary
 means of facilitating copying of software.  This Corresponding Source
 shall include the Corresponding Source for any work covered by version 3
 of the GNU General Public License that is incorporated pursuant to the
 following paragraph.
  Notwithstanding any other provision of this License, you have
 permission to link or combine any covered work with a work licensed
 under version 3 of the GNU General Public License into a single
 combined work, and to convey the resulting work.  The terms of this
 License will continue to apply to the part which is the covered work,
 but the work with which it is combined will remain governed by version
 3 of the GNU General Public License.
  14. Revised Versions of this License.
  The Free Software Foundation may publish revised and/or new versions of
 the GNU Affero General Public License from time to time.  Such new versions
 will be similar in spirit to the present version, but may differ in detail to
 address new problems or concerns.
  Each version is given a distinguishing version number.  If the
 Program specifies that a certain numbered version of the GNU Affero General
 Public License "or any later version" applies to it, you have the
 option of following the terms and conditions either of that numbered
 version or of any later version published by the Free Software

 GNU Affero General Public License, you may choose any version ever published
 by the Free Software Foundation.
  If the Program specifies that a proxy can decide which future

            How to Apply These Terms to Your New Programs
  If you develop a new program, and you want it to be of the greatest
 possible use to the public, the best way to achieve this is to make it
 free software which everyone can redistribute and change under these terms.
  To do so, attach the following notices to the program.  It is safest
 to attach them to the start of each source file to most effectively
 state the exclusion of warranty; and each file should have at least
 the "copyright" line and a pointer to where the full notice is found.
    <one line to give the program's name and a brief idea of what it does.>

    You should have received a copy of the GNU Affero General Public License
    along with this program.  If not, see <https://www.gnu.org/licenses/>.
 Also add information on how to contact you by electronic and paper mail.
  If your software can interact with users remotely through a computer
 network, you should also make sure that it provides a way for users to
 get its source.  For example, if your program is a web application, its
 interface could display a "Source" link that leads users to an archive
 of the code.  There are many ways you could offer source, and different
 solutions will be better for different programs; see section 13 for the
 specific requirements.
  You should also get your employer (if you work as a programmer) or school,
 if any, to sign a "copyright disclaimer" for the program, if necessary.

 ## Performance Notes
 The history and Saved pages use client-side filtering: when you type in the
 search box, the UI fetches the most recent 100 pastes (`limit=100`, the API
 maximum) once per query and filters/sorts them in the browser. Pastes beyond
 the newest 100 are not searched; a match count against the full total is still
 shown. This keeps search instant without a server-side query. If large
 instances need full search later, it will be a server-side endpoint (see
 issue #32).

 ```
 - `expires_in` is a Go duration string (`90m`, `6h`, `336h`). Omit for no expiry.
 - `visibility` is `public` or `unlisted`.
 - `burn_after_reads` sets how many reads the paste survives (default 1 when
  `burn_after_read` is true). A read is counted per unique viewer session;
  the same viewer returning within 15 minutes does not count again.
 - Response includes `id`, `url`, `raw_url`, `api_url`, `expires_at`,
  `created_at`, and a one-time `deletion_token`.
 Errors: `400` invalid body/content too large/duplicate slug, `401` password
 required, `404` paste expired/burned/gone, `413` content exceeds max bytes,
 `429` rate limited.

 # or via header: X-Paste-Password: secret
 ```
 The response includes `reads_remaining` (`null` when no read budget is set).
 ## Raw content
 ```bash
 curl http://localhost:8080/raw/{id}

 curl -X DELETE -H "Authorization: Bearer TOKEN" http://localhost:8080/api/pastes/{id}
 # ...or via query param; the creator browser (viewer cookie) may also delete without a token
 curl -X DELETE "http://localhost:8080/api/pastes/{id}?token=TOKEN"
 # hard delete immediately (requires the one-time deletion token)

 - `/history` — public paste history
 - `/mine` — pastes created from this browser
 - `/{id}` — view a paste
 - `/unlock/{id}` — password gate for protected pastes
 - `/raw/{id}` — raw content with original content type
 ## Expiry and deletion
 - Expired pastes are soft-deleted by a background sweeper (runs every minute).
 - Soft-deleted pastes are hard-deleted after a 7-day grace period.
 - Deletion tokens allow immediate hard delete.
 - Burn-after-read pastes are soft-deleted once the read budget is exhausted.

 # Attachments & Storage Backend Design (#38, #31)
 Status: research/design, no implementation. Consumers: paste cans (#4).
 ## Part A — Attachments: S3/MinIO vs filesystem-on-volume (#38)
 ### Options
 **Option 1: Filesystem on the k3s PVC (current 5Gi volume).**
 Store blobs under `<data-dir>/attachments/<paste-id>/<n>-<sha256-8>`, metadata in SQLite (paste_id, filename, size, sha256, mime, created_at).
 - Pros: zero new infra, zero new credentials, trivial backup (the volume backup job already covers the DB), atomic rename on write, works in dev and prod identically.
 - Cons: volume is size-capped (5Gi today; resizable but bounded); serving large files passes through the app process (no ranged-GET offload); multi-replica later would need RWX volume.
 **Option 2: MinIO via S3 API.**
 MinIO is already proven in this homelab (Outline). Store at key `<paste-id>/<n>`; same SQLite metadata row.
 - Pros: effectively unbounded capacity, presigned URLs (direct browser download, offloads serving from palette pods), ranged requests free, lifecycle rules could auto-expire orphaned objects.
 - Cons: another credential/secret to manage, another failure mode, MultipartForm still terminates at the palette pod (MinIO only helps *serving*, not *uploading*, unless we do presigned uploads — which breaks the cans multipart flow and the auth/unlock checks), backup now spans two systems.
 ### Key considerations
 - **Upload path is the same either way.** Palette receives `multipart/form-data` (cans need text items + file drops in one request), must enforce auth/password/burn rules server-side. A filesystem backend adds no upload complexity; S3 adds an extra hop (buffer → PUT to MinIO). Streaming straight from `multipart.Reader` to the sink works for both (`io.Copy` to a temp file, or to an S3 PUT with `Content-Length` known or multipart buffering).
 - **Size limits.** Everything is admin-tunable via the settings API (#40 pattern) — add `max_attachment_bytes` (default 10 MiB, hard server-side cap checked *before* reading the body via `Content-Length`, plus a counted reader during copy so chunked uploads can't lie). SQLite itself is not a constraint either way; the PVC is the real cap for Option 1.
 - **MIME handling.** Security-critical (pentest #34 already fixed a content-type XSS on `/raw`). Rules:
  - Never trust the client-declared Content-Type. Sniff the first 512 bytes (`http.DetectContentType`), intersect with an allowlist.
  - Serve from a dedicated route (`/{id}/a/{n}`) with `Content-Type` from the stored *sniffed* type, `X-Content-Type-Options: nosniff`, `Content-Security-Policy: sandbox`, `Content-Disposition: attachment` unless the type is on a safe-inline allowlist (text/plain, images, PDF at user opt-in).
  - Never render user HTML/SVG inline (`image/svg+xml` is XSS-capable — serve as `attachment` always, or store sanitized).
 - **Streaming & serving.**
  - Filesystem: `http.ServeContent` on the opened file gives ranged GETs, ETag, Last-Modified for free.
  - MinIO: proxy via `GetObject` + `io.Copy` (simple, keeps auth checks in palette) or presigned GET (faster, but URL embeds credentials-temporarily and bypasses palette's per-request auth — wrong for pastes with passwords/burn semantics). Given cans inherit password/burn parity (#4), **proxying is required, which erodes MinIO's main serving advantage**.
 - **Lifecycle parity.** Attachments must honor soft-delete grace and sweep: sweeper hard-delete also removes blobs (files: `os.Remove`; S3: `DeleteObject`), best-effort with logging; orphan sweep job compares DB rows to store contents.
 ### Recommendation
 **Filesystem-on-volume first.** At current scale (single replica, PVC-based deploy, one user + homelab traffic) it is simpler end-to-end and keeps serving/auth/lifecycle in one place. The internal API should be a narrow blob interface (`Put(ctx, key, r io.Reader, size int64) / Open(key) / Delete(key)`) — about 60 lines per backend — so **MinIO becomes a drop-in later** if attachments outgrow the volume. That's the honest middle path: filesystem default, S3-ready seam, no MinIO dependency until it pays for itself.
 ## Part B — SQLite vs Postgres vs Redis (#31)
 ### Assessment of SQLite at pastebin scale
 - **Driver**: modernc.org/sqlite (pure Go, no cgo) — slightly slower than mattn/go-sqlite3 but fine; single-writer semantics are the real constraint, not driver speed.
 - **Access pattern**: paste-heavy, write-rare/read-often; primary keys and small set of indexes (visibility+created, expires, deleted); no joins beyond can items. This is SQLite's best case.
 - **WAL mode** is already on (`journal_mode(WAL), busy_timeout(5000)`) — concurrent readers don't block the single writer.
 - **Numbers**: SQLite comfortably handles millions of rows and hundreds of reads/sec; WAL write throughput is thousands of small inserts/sec. A pastebin doing even 100k pastes (avg 10 KB = ~1 GB DB) is trivial. Reads: prepared `WHERE id=?` lookups at this size are sub-millisecond.
 - **Weak points to watch** (document, none urgent):
  1. Single writer — heavy concurrent create traffic serializes. Mitigation: already rate-limited (#2); fine until that's the bottleneck (unlikely).
  2. `LENGTH(content)` on every list row — fine now; if it shows up in profiling, store `size` as a column (schema already has a `Size` field; list queries could use it).
  3. Sweeper runs a table-wide `UPDATE`+`DELETE` on tick — indexed, fine.
  4. No network access to the DB file — locks palette to single-replica. Acceptable: current deploy is one replica.
 - **Redis is the wrong tool** here: it's a cache/queue, not a system of record. Pastes are durable data with expiry semantics already implemented in SQLite. Redis would only add an optional read-cache layer for hot pastes — pure complexity for zero measured need.
 ### Should we build a backend abstraction (SQLite default, optional Postgres)?
 Arguments for: multi-replica scaling later; "docker image env choice" sounds nice; Postgres gives real concurrency and network access.
 Arguments against: a `Store` interface covering the current query surface is a real refactor (sqlite-flavored SQL: `INSERT OR IGNORE`-style upserts, partial indexes, `?` placeholders are compatible but behaviors differ — e.g. `sqlite` driver pragmas, transaction isolation, `AUTOINCREMENT` semantics); two backends means two test matrices and two migration paths forever; and there is **no current need** — single replica, single writer, modest data.
 **Recommendation: stay SQLite-only. Do not build the abstraction now.**
 Specifically:
 1. Keep all persistence behind `internal/store` (already done in #35 — the package boundary *is* the abstraction, at zero cost).
 2. Avoid SQLite-specific SQL going forward where free (standard placeholders, no `RETURNING` quirks) — cheap discipline that keeps a future port honest.
 3. Define the trigger conditions for revisiting, and write them down:
   - multiple replicas needed (scale-out), or
   - sustained WAL write contention (busy timeouts observed in logs), or
   - DB file > ~5-10 GB, or
   - a concrete user request for a Postgres-backed image.
 4. When a trigger fires, port `internal/store` to Postgres behind an interface extracted *then* — the refactor is mechanical against a real need, instead of speculative complexity now.
 5. For the docker image: `PALETTE_DB_PATH` env already implies the deployment choice; no extra backend knob needed.

 # Design: Cookie-Based Preferences and Access Keys (#30)
 Status: design note — no implementation yet.
 Related: #37 (vwr viewer cookie), #34 (HMAC unlock cookie), #26 (creator auto-unlock), #36 (settings gear).
 ## Current cookie surface
 | Cookie | Purpose | Lifetime | Flags today |
 |---|---|---|---|
 | `vwr` | Anonymous viewer id; scopes `/mine` history and burn-after-N per-viewer dedupe; client-sent `vwr` also authorizes delete | 1 year | `HttpOnly`, `SameSite=Lax`, `Path=/` |
 | `pw_<id>` | Per-paste password unlock token = HMAC(paste id, PALETTE_UNLOCK_SECRET) | 1 hour | `HttpOnly`, `SameSite=Lax`, `Path=/` |
 | `tok_<id>` | One-time deletion-token handoff after create | 60 s | `HttpOnly`, `SameSite=Lax`, `Path=/` |
 The access-key feature is an extension of the `pw_<id>` pattern, not a new mechanism.
 ## Part 1: Preference storage
 ### What settings
 Only settings the *creator* sets when writing a paste, so the "new paste" form
 can pre-fill them:
 - Default language (`lang`)
 - Default expiry (`expires_in` / custom expiry)
 - Burn-after-N-reads default
 - Password-protect-by-default toggle (checkbox pre-checked; the password itself is never stored)
 - Default visibility of the "raw" link, if such a toggle exists
 - Collapsed/expanded state of the settings gear panel itself
 Never stored in cookies: passwords, access keys for pastes the user hasn't
 unlocked, deletion tokens (beyond the existing 60 s `tok_` handoff), anything
 typed into the paste body or title fields (existing rule: auto-detect must not
 overwrite user-typed content).
 ### One cookie, not many
 A single `prefs` cookie holding a compact JSON object:
 ```
 prefs={"lang":"go","exp":"1h","burn":0,"pw":1}
 ```
 - One cookie avoids the browser per-domain cookie count (typically 50+ per
  domain; Chrome 180) eating the budget that per-paste access-key cookies need.
 - Per-paste cookies (`pw_<id>`) are inherently name-per-paste and cannot be
  consolidated — that's the constraint that makes a single `prefs` cookie
  mandatory rather than stylistic.
 ### Size limits
 - RFC 6265: user agents SHOULD support at least 4096 bytes per cookie. Keep
  `prefs` under 256 bytes of JSON — it holds a handful of short enum values.
 - Server behavior: if the cookie is present but oversized/invalid JSON, ignore
  it silently and serve defaults. Never reject a request over a bad preference
  cookie.
 - Validate on the server (allowlist of known values); a cookie is untrusted
  input like any header.
 ### Flags
 `HttpOnly; SameSite=Lax; Path=/; Max-Age=31536000; Secure` (Secure once the
 prod instance serves HTTPS — it will, behind the letsencrypt IngressRoute;
 dev on plain HTTP needs the flag conditional on config).
 Preferences are not sensitive, but `HttpOnly` costs nothing and keeps script
 from mutating them; `SameSite=Lax` matches the existing cookies.
 ## Part 2: Access-key cookies
 ### Goal
 "Remember unlocked pastes on this browser" — after entering a password (or
 after creating a private paste), subsequent visits skip the unlock form. This
 extends `pw_<id>` from a 1-hour session convenience to a durable capability.
 ### Design: extend `pw_<id>`, don't invent a new scheme
 The token is already HMAC(paste id, PALETTE_UNLOCK_SECRET) — unforgeable and
 per-paste (fix for the #34 bypass). Changes:
 1. **Opt-in checkbox on the unlock form** ("remember on this browser") and a
   matching checkbox/note at creation time. Default OFF. Non-consenting
   visitors keep the current 1-hour cookie.
 2. **Extended lifetime** when opted in: `Max-Age = min(paste expiry, 90 days)`.
   The cookie must never outlive the paste — derive the cap from the paste's
   `ExpiresAt` at unlock time. Burn-after-N pastes: cap short (e.g. 24 h),
   since the paste may burn at any read.
 3. **Name collision**: paste ids are fixed-length server-generated, so
   `pw_<id>` names stay bounded (~40 bytes each). With the 50-cookies-per-
   domain budget, cap remembered pastes at ~30: when minting the 31st, drop
   the oldest expired-paste cookies server-side (server knows which ids are
   expired/deleted; send expired `Set-Cookie` with `Max-Age=0` to reclaim).
 4. **Delete authorization interplay**: today a client-sent `vwr` matching the
   paste's ViewerID authorizes delete. Access-key cookies grant *read*
   capability only. Do not let a `pw_<id>` cookie authorize deletion — that
   would mean cookie theft escalates from "read a paste" to "destroy it".
   Delete stays bound to `vwr` or the deletion token.
 ### Scoping
 - Keep `Path=/` (paste URLs are `/{id}` at the root; per-paste `Path=/{id}`
  would work but saves nothing and complicates cleanup).
 - Per-paste scope via the cookie *name* is the existing, tested pattern —
  no shared "access key ring" cookie. A consolidated `keys` cookie would
  mean one stolen cookie exposes every remembered paste at once.
 ## Part 3: Security considerations (honest accounting)
 - **XSS exfiltration**: `HttpOnly` prevents JS from *reading* the cookies, but
  not from *using* them — an XSS payload can simply `fetch('/<paste-id>')` and
  exfiltrate the content through the page the cookie unlocks. HttpOnly raises
  the bar (drive-by script can't dump the jar to an attacker server in one
  request), it does not make access-key cookies safe. This is a real
  limitation, not a solved problem. Mitigations in order of value:
  1. Fix the stored-XSS class at the source — #34 already allowlisted
     content-types on `/raw`; the standing debt items (CSP, X-Frame-Options,
     Referrer-Policy) directly reduce cookie-use exfiltration and should land
     before or with this feature.
  2. Keep access-key cookies opt-in, so the blast radius is bounded to users
     who accepted the tradeoff.
 - **Cookie theft = paste access**: anyone holding `pw_<id>` can read that
  paste until the cookie or paste expires, from any machine. That is inherent
  to capability cookies. Consequences accepted deliberately: pastes here are
  ephemeral (1 min–1 yr expiry), passwords are low-stakes share convenience,
  and there are no user accounts to compromise. Document this in the UI copy
  ("stores unlock access on this browser").
 - **Shared machines**: a remembered cookie defeats the password for the next
  user of the browser. The opt-in checkbox with plain-language copy is the
  mitigation; do not default it on.
 - **Cookie tossing / fixation**: a subdomain attacker could try to force
  cookies; palette is a single host, no untrusted subdomains. `SameSite=Lax`
  blocks cross-site attachment of the cookies on form posts to unlock
  endpoints.
 - **Multi-instance / secret rotation**: tokens are HMACs under
  `PALETTE_UNLOCK_SECRET`; rotating the secret silently invalidates all
  remembered cookies (acceptable — next visit re-prompts). Both dev and prod
  k3s instances need the same secret only if sharing a domain, which they do
  not.
 - **Preferences cookie**: not security-sensitive, but still validate/allowlist
  server-side to avoid it becoming an injection sink into templates.
 ## Recommendation
 Implement in two small, separately reviewable pieces:
 1. **`prefs` cookie** (do first, low risk): single JSON cookie < 256 bytes,
   server-validated allowlist, `HttpOnly; SameSite=Lax; Max-Age=1y`, drives
   only form pre-fill. Ship with #36's settings gear.
 2. **Extended `pw_<id>` opt-in** (second, security-sensitive): opt-in checkbox,
   Max-Age capped by paste expiry (90-day ceiling, 24 h for burn pastes),
   oldest-cookie eviction at ~30 pastes, no delete authorization from access
   cookies, and land the CSP/X-Frame-Options hardening debt from #34 in the
   same or preceding change. UI copy must disclose that the cookie preserves
   paste access on the browser.
 Rejected alternatives: single consolidated access-key cookie (aggregate theft
 risk, and the per-domain cookie-count argument cuts the other way for keys —
 consolidation maximizes what one stolen cookie unlocks); localStorage for
 preferences (XSS-readable, no benefit over HttpOnly cookies here); server-side
 accounts/session table (out of scope — Palette is deliberately anonymous).

 # Design: Optional client-side E2E encryption for pastes and files
 - **Issue:** #39
 - **Status:** Design (no implementation in this PR)
 - **Related docs:** [docs/API.md](../API.md)
 ## 1. Goals and non-goals
 **Goals**
 - Let any paste (or can item) be stored server-side as ciphertext only.
 - Zero plaintext knowledge by the server: storage, logs, backups, DB dumps contain no readable content.
 - Pure browser implementation using WebCrypto; no new server dependencies.
 - Encrypted pastes must still work with expiry, hard/soft delete, deletion tokens, visibility, slugs, rate limits.
 **Non-goals (v1)**
 - Anonymous, account-less E2E; Palette stays server-trusting with browser cookies.
 - Sharing via link fragments (`#key`) is optional sugar, not a required transport.
 - Search *of encrypted content*, server-side language detection, or server-side highlighting on encrypted pastes — these are structurally impossible and out of scope (see §5).
 - Signing, deniability, forward secrecy across pastes, PFS, post-quantum crypto.
 **Threat model (explicit).** This protects against a *passive server compromise* — a DB dump, backup leak, or disk image of the server's SQLite file. It does **not** protect against:
 - A fully malicious / compromised Palette server serving backdoored JavaScript: any JS-delivered crypto can be backdoored (key exfiltration via JS) regardless of primitives. This is the fundamental limit of a JS-in-browser E2E scheme.
 - Malware on the viewer's device, or shoulder-surfing of the password.
 - Traffic analysis, timing, or metadata (title, size, expiry, IP, viewer cookie).
 - A attacker who compromises the server *while the creator's browser is open* and alters JS before encrypt.
 Be explicit in user-facing copy: "encrypted at rest; the server cannot read your paste" is accurate — "the server can never see your paste" is not.
 ## 2. Crypto primitives and flow
 ### 2.1 Recommended parameters
 | Parameter | Recommendation | Notes |
 |---|---|---|
 | Cipher | **AES-256-GCM** | `AES-GCM` with a 256-bit key, per-paste random 96-bit IV/nonce. WebCrypto built-in, hardware-accelerated, authenticated. |
 | KDF | **PBKDF2-HMAC-SHA-256** | 600,000 iterations (OWASP 2023+ recommendation), 16-byte random salt. |
 | Argon2id | **Not in v1** | WebCrypto has no Argon2id; a JS/WASM Argon2 implementation is an extra supply-chain dependency and is an asymmetric liability: a script the server could swap can't be load-bearing for security anyway. Add later via `argon2id` WASM with SRI pinning + CSP (`script-src 'self'`) if needed. |
 | Salt | 16 random bytes per paste, stored in the clear alongside ciphertext | Unique per paste, never reused. |
 | IV | 12 random bytes per encryption | With ~2^32 encryptions per key this is negligible; each paste has its own key anyway. |
 | Key check value | See §2.2 | Catches wrong passwords without a server round-trip and prevents trash writes. |
 ### 2.2 Flow (create)
 1. User checks "Encrypt" and enters an encryption passphrase (distinct from any access password) in `/new`.
 2. Browser generates `salt` (16 B) and `iv` (12 B) via `crypto.getRandomValues`.
 3. `crypto.subtle.importKey("raw", passphrase, "PBKDF2", false, ["deriveKey"])` →
   `crypto.subtle.deriveKey(PBKDF2-SHA-256, 600k iterations, salt, {name:"AES-GCM", length:256}, false, ["encrypt","decrypt"])`.
 4. Generate a 32-byte random **DEK** (`crypto.getRandomValues(32)`).
 5. Content encryption key check: `iv_ckv`, `encrypted_content = AES-GCM-256(DEK, iv, content)`.
 6. **Key check value (KCV):** compute `AES-GCM-DEK(random 16 bytes)` — a small token encrypted *under the DEK*, stored as `key_check` blob. This is decrypted with the derived key; on wrong password GCM auth fails and the client can show "wrong key" without asking the server to burn a read.
 7. Wrap the DEK with the KEK: `wrapped_dek = AES-GCM(KEK, iv_wrap, dek)`.
 8. The stored envelope format:
   ```
   {
     v: 1, kdf: "PBKDF2-SHA256", iterations: 600000, salt_b64, iv_b64,
     kdf_salt_b64, wrap_iv_b64, wrapped_dek_b64, key_check_b64, ciphertext_b64
   ```
   The `v` field allows migrating to Argon2id later without a breaking change.
 8. POST the envelope (base64) as `content`, with an `encryption` metadata object alongside (see §3.1).
 ### 2.3 Flow (view)
 1. User provides the passphrase via form field, or the key arrives in the URL `#fragment`. The encryption passphrase is a separate field from any access password.
 2. Fetch `/api/pastes/{id}` (with access password in the usual field if the paste is also password-gated).
 3. Derive KEK from passphrase+salt, unwrap DEK via key_check / unwrap step.
 4. Decrypt content with the DEK; on `OperationError` → "wrong passphrase" UI state (retries are client-side only; no re-fetch, so no extra burn-after-read charge).
 5. Language detection happens client-side (e.g. highlight.js auto-detect) on the decrypted plaintext.
 ### §2.4 File and can items
 Files in cans: encrypt each file with its own DEK and store the same envelope. Cans' `json_items` content fields each carry their own envelope. Files keep their mime type in cleartext metadata; only the bytes are encrypted. The can's title stays plaintext (unless the whole can is encrypted, v2).
 ## 3. API shapes
 ### 3.1 Create request
 Existing fields unchanged. New optional `encryption` object:
 ```json
 POST /api/pastes
 {
  "content": "<base64 envelope>",
  "encryption": {"v": 1, "kdf": "PBKDF2-SHA256", "iterations": 600000,
                 "salt": "b64", "iv": "b64", "key_check": "b64"}
 }
 ```
 `encryption` is non-secret KDF metadata for UI display; the server treats `content` as opaque bytes and MUST NOT inspect it for encrypted pastes (no detection, no highlighting prep, no search indexing) — enforced where content is written, not per-handler.
 The full envelope can also just live inside `content` (server-opaque); the `encryption` object carries only non-secret KDF metadata the list views need (e.g. to show a 🔒 icon).
 ### 3.2 Create response
 Unchanged shape: `id`, `url`, `raw_url`, `api_url`, and the one-time `deletion_token` documented in docs/API.md.
 ### 3.3 Get response
 `GET /api/pastes/{id}` response gains:
 ```json
 {
  "id": "abc123",
  "content": "BASE64_ENVELOPE",
  "encryption": {"v":1, "kdf": "PBKDF2-SHA256", "iterations": 601570, "salt": "b64", "iv": "base64", "key_check": "b64"},
  "reads_remaining": null
 }
 ```
 `language` is `"encrypted"` or `null` so clients don't run detection on ciphertext. `raw_url` also serves the envelope; the `/{id}` page ships it to the browser, which decrypts in place.
 ### 3.4 Raw endpoint
 `GET /raw/{id}` returns the envelope as `application/octet-stream` with a suggested filename like `{id}.e2e.txt` and `Content-Disposition: attachment`. This is deliberate: a "download encrypted blob" is what a non-browser client can do with it anyway.
 ### 3.5 List views / mine / public
 List endpoints return `has_encryption: true` instead of content; show a lock icon. Do not include ciphertext in list responses (size, and no reason to ship ciphertext to every viewer's list view) — `GET /api/pastes/{id}` remains the only endpoint that returns the envelope.
 `/api/mine` (creator's own browser) may include the envelope for convenience; `/api/public` returns metadata only.
 `/api/guess-language` rejects encrypted content with `400 "content is client-encrypted"` — detection needs plaintext; clients detect after decrypting.
 Delete, redeem, rate limits, expiry, sweeper, deletion tokens, visibility, slugs, and can CRUD are unchanged — the server never inspects content for these, so opaque content is a no-op path.
 ## 4. Interplay with existing features
 | Feature | Impact | Mitigation |
 | Burn-after-read | Budget is charged on fetch, exactly as today; the server cannot know whether decryption succeeded, so a viewer fetching with the wrong key burns a read they can't use. | Decrypt retries are client-side, so only the first fetch charges the budget. Clear UX copy. |
 | Password-protected + encrypted | Both can coexist and are independent: the access password is an HTTP 401 gate; the encryption passphrase never leaves the browser. If both are set, all three secrets are needed (URL + access password + passphrase). Warn if the user enters the same value in both fields. |
 | Encryption-only pastes | Supported with no access password: URL + passphrase (or fragment key). Default is passphrase; fragment key is opt-in with a warning. |
 | Search | Structurally impossible over ciphertext. Server search just skips encrypted pastes; client-side search within a single decrypted paste works fine. No global encrypted-content search — accept the loss, document it. |
 | Language detection / highlighting | Server-side detection/highlighting impossible; returns `language: null`. Client-side detection via highlight.js auto-detect on decrypted plaintext (client already loads it for password gate pages). |
 | Cans/files | Per-item envelopes (own DEK each), per §2.4. | Consider a can-level KEK (one passphrase unlocks all items). |
 | Expiry/sweeper/delete/redeem | Unchanged — server never inspects content for these. |
 | List views (`/api/public`, `/api/mine`) | Additive `has_encryption: true` flag; list responses do not include ciphertext (`/api/mine` may include the envelope for the creator's own convenience). |
 | guess-language endpoint | Reject with 400. |
 | Fork / edit | Re-encryption needs the passphrase in the browser; v1 disables forking encrypted pastes. | Document the limitation. |
 ## 5. What breaks, stated plainly
 - **Search across encrypted pastes: impossible.** Accept the loss. (If ever needed, client-side index in IndexedDB for the creator's own pastes — v2+.)
 IndexedDB only helps the creator, not other viewers; still not global search. Accept the loss.
 - **Server-side language detection and highlighting: impossible.** Client-side detection on decrypted plaintext. Server returns `language: null` and the client detects.
 - **Burn-after-read is weakened in one specific way:** the budget is counted on fetch, not on successful decryption. A viewer who fetches but can't decrypt (wrong/lost key) burns a read they can't use. Mitigations documented in §4 table. The server can still count fetches (which is what burn-after-read actually is, even today: it counts fetches, not "reads" in any content-aware sense). So burn-after-read still works — it counts fetches — it's just that a failed decryption still consumes budget. This is acceptable and just needs UX copy. Optionally: don't decrement on failed decryption is *not possible* the server can't tell, so it's fetch-based, period. (It already is today.)
 - **Raw endpoint semantics change:** `/raw/{id}` can no longer serve readable raw text. It serves the ciphertext envelope. Scripts that curl raw pastes will get base64 envelope instead of text. Document as a breaking-ish change for encrypted pastes only; unencrypted pastes unchanged.
 - **Existing /api/mine, /api/public list shapes gain a flag** (additive, non-breaking).
 - **Copy-to-clipboard of decrypted text stays client-side**, fine. "Copy raw" on an encrypted paste copies the envelope — label it clearly.
 ## 5. UX for key sharing
 ### 5.1 Three sharing modes
 | Mode | What's shared | Security level | Use case |
 |---|---| malformed JSON / wrong key | | |
 | Mode | What's shared | Strength | Use case |
 |---|---|---|---|
 | **Passphrase** (default) | URL + passphrase out-of-band (Signal etc.) | Good — two channels | Team snippets, sensitive configs |
 | **Passphrase + access password** | URL + access password (401 gate) + passphrase | Strong — two secrets, two channels | Highest sensitivity |
 | **Random key in `#fragment`** | URL containing `#key=<b64>` | Weak — single channel; anyone with the full URL has both parts. Copy/paste into chat defeats it entirely. | One-click convenience sharing |
 Browsers never transmit `#` fragments to servers; still set `Referrer-Policy: no-referrer` site-wide and offer separate copy buttons for URL and key. Key-in-fragment ships with a warning and stays opt-in.
 ### 5.2 Create page (`/new`) UX
 - "Encrypt content" toggle → reveals passphrase field + strength meter + generate-random-key button.
 - When encrypting, hide the server-side language dropdown; the client detects language after decryption.
 - Two separate inputs with distinct labels: "Access password (checked by the server, 401 gate)" and "Encryption passphrase (never leaves your browser)". If both hold the same value, warn.
 ### 6.2 View page (`/{id}`) UX
 - If `encryption.kdf` is present → show key entry UI (after the access-password 401 gate, if that also applies).
 - After decrypt: normal render pipeline, language detected client-side.
 - "Wrong passphrase" retries never re-fetch, so they never burn extra reads.
 ## 7. Backwards compatibility and migration
 - Additive JSON fields only; unencrypted pastes behave identically. No schema changes (envelope is stored in the existing content column/TEXT; verify column size allows envelope overhead (~2× base64 + ~200 B header).
 - Server-side validation of encrypted pastes: only structural checks (base64 decodes, size ≤ max bytes). No crypto in the server.
 **Server implementation cost is genuinely small** (est. 2-4 days): pass through content untouched, add `encryption` metadata column or embed in content, skip detection/indexing when `encryption` is present, list flag. The server never does crypto. All crypto is client-side JS (~150-300 lines, no build-step change if using WebCrypto alone).
 **Argon2id later:** add `kdf: "argon2id"` to the envelope `v: 1` (m=64 MiB, t=3, p=1) via a SRI-pinned WASM module, with CSP `script-src 'self'` + SRI on the script tag. Envelope `v` field already allows this.
 ## 8. Recommendation
 **Build it, as an opt-in checkbox, passphrase mode only in v1.**
 - Server cost is small (pass-through + skip detection/indexing + list flag), client cost moderate (WebCrypto only, no new deps).
 - It closes the biggest real-world risk for a public pastebin: a DB/backup leak exposing every paste ever written.
 - Skip Argon2id in v1; envelope `v` field provides a migration path.
 - Key-in-fragment mode: build the plumbing (fragment parsing) but hide behind "advanced"; default remains passphrase.
 **Do not build:** server-side search over encrypted content, server-side highlighting of encrypted content, decrypt-on-server "preview" mode, or any server-side crypto.
 ## 9. Open questions
 1. Size limits: base64 expansion (~4/3×) plus ~200 B envelope overhead; the existing max-bytes / 413 limit applies to the envelope bytes the server stores. Do not compress before encrypting (CRIME-style weaknesses).
 2. Fork/edit of encrypted pastes: disabled in v1, revisit.
 3. Should `/api/mine` include the full envelope in list view? Leaning yes (creator's own browser can decrypt); note the larger payload.
 4. Should there be a "verify passphrase" second field at create time (type-twice), or rely on the KCV check at view time? KCV at view time suffices; type-twice adds friction at create. Rely on KCV, skip type-twice.
 5. CSP/Referrer-Policy hardening: `Referrer-Policy: no-referrer` site-wide is worth doing regardless of this feature (it also benefits unencrypted pastes).
 6. Cans: per-item DEKs wrapped by a single can-level KEK (one passphrase unlocks all items) — better UX, slightly more envelope design work. Defer detail to implementation.
 ## 10. Alternatives considered
 | Alternative | Why not in v1 |
 |---|---|
 | Argon2id via WASM in v1 | Extra JS dependency the server could swap → can't be load-bearing; PBKDF2-600k is adequate for a pastebin. Defer. |
 | Server holds half a key (2-of-2 with server-held share) | Re-introduces server trust; defeats the purpose. |
 | age-format envelopes | Nice CLI interop but no WebCrypto-native support; adds a JS dependency. Defer. |
 | PGP / S-MIME | Poor browser UX; heavy dependencies. |
 | Server-side encryption with server-held keys | Not E2E; that's "encrypted at rest", already covered by disk-level encryption. |
 | PrivateBin-style fragment key only | Single-channel sharing is a footgun; keep passphrase as default. |
 | libsodium / tweetnacl | Solid but unnecessary; WebCrypto covers AES-GCM + PBKDF2 natively. |
