/* games.css — TinkyGames overlay + hub + per-game UI.
 *
 * Namespace: .tg-* — all rules scoped, won't bleed into board-builder or
 * kiosk UI. AAC-first: minimum 80px tap targets on game controls (board
 * is 48dp/64dp because users tap rapidly; games are tappable once per
 * direction so the larger target wins).
 *
 * Color-blind safety: blues + yellows + purples; never red+green-only as
 * the only signal.
