/* Stylesheet for the statically generated /guides pages (see scripts/build-guides.mjs).
   Lives in public/ rather than src/ because these pages are generated outside Vite and so
   can't resolve its content-hashed asset filenames -- this needs a stable, unhashed URL, the
   same reason the favicon lives here.

   Palette values are copied from src/styles.css rather than shared, since a static page can't
   import the app's CSS. Keep them in sync if the palette changes.

   Dark mode keys off prefers-color-scheme here, NOT the app's data-theme attribute: that's an
   account-level preference set by React after login, and these pages are public and have no
   session to read it from. Following the OS is the only signal available. */
