/* The public bar and footer (#552, epic #539): the markup comes from
   src/shell/render.ts on every public page (static pages, the Worker's blog
   pages and the React pages), so this is the one stylesheet for it. It lives
   in public/ under a fixed name because the blog pages, rendered by the
   Worker with `style-src 'self'`, link it without a build manifest.
   From the approved mockup (https://claude.ai/artifact/JqGSUPAKf8wbaYHcU9ktBF).
   Light only, like the app (#137). Everything is under .sh-* so it neither
   leaks into nor picks up the pages' own styles. */
