/* ===========================================================================
   CrossDesk — public site stylesheet.

   Shared by every static page under frontend/public/ (home, benchmarks,
   methodology, governance, licensing, regulatory, news, about). Same palette
   as the app (frontend/src/styles.css) and the showcase deck, so a visitor
   moving between site, deck and desk is never handed to a different product.

   GOLD IS RESERVED for one thing: an officially struck value. Nothing else on
   the site is painted gold.

   Fonts are self-hosted (public/site/fonts/) — no external CDN. The display
   face falls back to the system serif stack.
