Show HN: O-O – HTML/bash polyglot files that rewrite themselves (update)

Update on o-o (https://news.ycombinator.com/item?id=47052729) — polyglot HTML/bash files that research and rewrite themselves.

New stuff: files sync to each other. Edit the CSS in any file, run --sync css, and every sibling file gets the update. No build tool, no shared imports. Just files copying sections between themselves using markers.

Dark mode, responsive layout, search — the usual. Still zero deps beyond bash and Claude Code.
