   corral.css — the /corral/ project page only.

   Loaded ON TOP of site.css and uses its tokens (--bg-card, --accent-copper,
   --font-mono, …) rather than restating any colour. Kept out of site.css on
   purpose: site.css is shared with the hand-authored home page and every
   generated note, and its ?v= cache-buster is referenced from two files, so a
   page-local concern gets a page-local file.
