The .deck grid used '1fr 300px'; the 1fr editor column could not shrink below its min-content, expanding the grid to ~1000px at 800px viewports and pushing .pane-r to right=980 (document.scrollWidth 980 vs innerWidth 800). Use minmax(0, 1fr) so the editor column can shrink; the editor itself already clips/scrolls its own content. Verified with a CDP overflow probe at 800x600, 375x812, 1400x900 and 700x600: scrollWidth == innerWidth at all four.
Palette
Palette is a fast, self-hosted pastebin. One Go binary, a SQLite database, and a web UI for sharing text and small files.
Note
✨ This project was built by AI — GLM 5.3 Flash on the Hermes Agent harness, with a human in the loop.
Features
- Text pastes and cans (multiple items in one share)
- File attachments (one file per paste, up to 25 MB)
- Password protected pastes
- Expire after a specified time
- Burn after a number of views
- Custom URLs
- Syntax highlighting with language auto-detection (go-enry)
- Public paste listing with search, sort and pagination
- Cookie based saved pastes and settings
- Five base themes (midnight, smooth, pastel-lavender, pastel-peach, pastel-cloud), each with a dark and light variant
- Dark mode toggle in the topbar and settings, with a configurable default
- Polished code viewer: line-number gutter sized to the widest number and pinned during horizontal scroll, optional line wrap, jump-to-top/bottom buttons, and theme-aware scrollbars

Get Started
Docker
docker run -p 8080:8080 -v palette-data:/data git.archfox.org/poslop/palette
The SQLite database lives in the /data volume inside the container.
Docker Compose
See docker-compose.yml for a ready-to-use example with every environment variable documented, including which are required (only the /data volume) and which are optional.
