   Avari — shared stylesheet
   Used by product.html, studio.html, about.html.

   index.html keeps its own inline CSS (per CLAUDE.md's single-file
   rule) and is deliberately untouched. Duplicating ~600 lines of it
   across three more pages would have been worse than one shared file,
   and a plain <link> adds no build step — the "no bundler" constraint
   still holds.
