/* DataHub
   ------------------------------------------------------------------
   Single stylesheet for the rendered pages and the gate. Dark by design:
   the 3D viewer and the Stream player are dark, and scanned material
   reads better against a deep ground. No framework, no inline styles
   (the CSP forbids them), system font stack so nothing is fetched.

   Classes keyed by a data type (badge-model, media-video, viewer-model...)
   take the type's id from src/types.js; a new type gets its own rules
   under "Badges" and "Cards" below. */

/* Country flags. Windows has no flag emoji and draws the two letters
   instead ("BZ" for Belize), so flags come from this font everywhere: the
   Twemoji flags (CC BY 4.0, credited on the privacy page), subset by
   TalkJS (country-flag-emoji-polyfill, MIT; licence beside the file). The
   unicode-range limits it to flag characters, so a browser downloads it
   only for a page that shows a flag, and no other text changes. To
   upgrade, copy the package's dist/TwemojiCountryFlags.woff2 and
   LICENSE.md into css/fonts under the new version and point src here. */
