/* The Quiz Club — landing page (index.html only).
   Loaded AFTER styles.css: tokens, .card, .btn and .badge come from there
   verbatim; this file adds only what the landing needs on top.

   The page is a slide deck: the body never scrolls, the .track holds all
   slides stacked vertically and moves one viewport at a time. A slide whose
   content overflows scrolls INTERNALLY first — flipping only happens at its
   edge, so nothing is ever unreachable. prefers-reduced-motion (and no-JS)
   degrades to a plain scrolling page. */
