Wrap ON breaks long tokens mid-word; no horizontal scroll while wrap enabled (#152)

- codebody/editor: overflow-wrap anywhere + word-break break-all + overflow-x hidden under html[data-wrap]
- code container and mobile .float also hidden overflow with wrap on
- topbar mobile: tighten gap/padding/nav link padding so nothing overflows at 375px

Fixes #152
