/* The challenge/quiz overlay — component CSS for public/js/quiz-view.js.
 *
 * Every colour here comes from a custom property defined in base.css
 * (--fg, --bg, --muted, --border, --accent, --accent-fg, --card,
 * --card-raised, --good, --bad, --warn, --radius); nothing in this file
 * hardcodes one, so the light/dark toggle keeps working without this file
 * knowing that it exists.
 *
 * Only one of the four screens (`quiz`, `waived`, `reveal`, `picker`) is ever
 * mounted at a time — quiz-view.js guarantees that — so they all share one
 * `.quiz-overlay` / `.quiz-modal` shell and differ only in their body content.
