/* ---------------------------------------------------------------
   TermSentinel static guide pages — shared stylesheet.

   These pages are plain server-rendered HTML, not part of the Vite/React
   build. They intentionally do NOT pull in Tailwind or the component
   library; that would require the guides to be part of the SPA bundle,
   which defeats the point (a crawler needs real HTML, not a script tag).

   Values below are copied by hand from client/src/index.css so the visual
   system matches exactly: Fraunces (display), Work Sans (body), JetBrains
   Mono (data/eyebrow). Colors are the same HSL triples as the live app's
   :root and .dark blocks. There is no JS theme toggle here — dark mode
   follows the OS via prefers-color-scheme, which is the only signal a
   static, no-JS-required page can use.
