/* ============================================================================
 * PlainLogic mobile-game components — assets/css/games-mobile.css
 *
 * Styles for window.PlainLogicGamesMobile (assets/js/games-mobile.js):
 * the game topbar (back link + title + motion toggle), HUD chips/badges,
 * HUD buttons (restart / undo / redo), and the collapsible "What you
 * learned" panel. Companion to assets/css/games.css — never overrides it.
 *
 * Uses the site tokens from lab.css (light + dark via [data-theme]).
 * Mobile-first: 375px clean, no horizontal overflow. Touch targets >= 44px,
 * no hover dependency. Correct/incorrect is never color-only.
