/* Quiz-specific styles.

   The look comes from the ADA design system in /ada.css (generated from the
   `ada-brand` repo by `npm run brand:sync`): buttons, cards, headings, form
   fields, badges, stat tiles and the dark Hero band are all its `ada-*`
   classes. This file only adds what a live quiz needs and the system has no
   component for (answer tiles, countdown, podium, projector sizing), and it
   builds those from the system's `--ada-*` tokens. */
