/* example-cards (.contracts/example-cards.md): the «Example song» block of the home page and the occasion pages
   (js/examples.js). Every rule is keyed on .exs / .exc, which only examples.js makes, and only on a page with cards:
   a page without cards keeps an empty mount with no box. The cover is the quiz's sound-step cover (sound-panel.css
   .snd-tile: a two-color gradient per genre, the name in white, the symbol big and white in the corner), the 13 color
   pairs repeated from sound-panel.css (whose rules are keyed on #snd) — test/example-cards.test.ts keeps them equal.
   Every control 44 px or more. */
