/* QUIZ-WORLD home (/quiz-world/ for visitors): the colourful Self Quiz opening, rebuilt on the project palette.
   Loaded last on home.html. Light, sepia and dark all come from the tokens in qw-buttons.css (no hard-coded colours).
   Bands alternate: a glowing hero, a paper band with six coloured path cards, a tinted teacher band, numbered steps,
