/* ============================================================
   Oak-Ed – Web Awesome base styles
   ============================================================ */

/* --- Fonts: self-hosted, not the Google Fonts CDN ----------------------
   These live here rather than in a per-surface stylesheet because this file
   is the one thing every Oak-Ed surface loads — including the static games
   catalogue, which Caddy serves off disk and which links this file over
   /static/.

   Not the CDN, for two reasons. Privacy: these pages know who is reading
   (the shared header shows the signed-in learner's name) and children load
   them, so they shouldn't leak viewer IPs and referrers to a third party.
   The static catalogue used the CDN back when it was anonymous — bringing it
   into the shared, viewer-aware chrome is what changed that. Reliability:
   Caveat and Patrick Hand are used throughout the games' own gameplay UI, not
   just as decoration, so a blocked or slow third-party request is a visibly
   broken game rather than a cosmetic wobble.

   collectstatic + WhiteNoise give hashing, far-future caching and
   compression, and ManifestStaticFilesStorage rewrites the relative url()
   refs below automatically. Licences: static/fonts/OFL.txt. */
