/* ============================================================
   Termdeck — site.css  (shared marketing sub-page components)
   The /vs/* and /blog vocabulary (vs-*, post-*), dark agent-ai
   theme. Loads AFTER home.css and only ADDS: theme, tokens, nav,
   footer, buttons, code and links all come from home.css. Every
   marketing page loads both (one head-assets partial for all), so
   nothing here may restyle a class the homepage uses.
   Replaced homepage.css + vs/vs.css (the paper theme) 2026-08-03,
   when the sub-pages joined the homepage's chrome.
