/* ── Play (#/play) ───────────────────────────────────────────────
 * The five games, drawn with My kanji's pieces (style.css): the section is
 * a .mk, the list a .mk-list of hairline rows, the switches .seg, the keys
 * the review's .rv-kbd. Nothing here declares a colour: every one is a
 * token from base.css or style.css's :root. A right answer is lit with the
 * Collection's tile wash; a wrong one is dashed in the danger tone, and both
 * carry a mark and words, never colour alone. Nothing is fixed to the
 * viewport, because an embedded Yomu is as tall as its page (CLAUDE.md). */
