/* Shared styles for the marketing site: the landing page (/) and every generated
   documentation page (/docs/). It lives in public/ rather than in src/ because the
   docs pages are written out by build/docsPlugin.ts, OUTSIDE Vite's module graph —
   they cannot import a hashed asset, so both halves of the site link one stable
   /site.css instead. The app itself (/app/) does not use this file; it has Tailwind.

   Colours track the app's own palette (Tailwind neutral + blue-600) so launching it
   does not feel like landing on a different product. */
