/* ============================================================
   りんかカードゲーム（りんかメモリー／りんかかくれんぼ）2026-09-26 作り直し
   - #rinka-games-app（.rinka-cg-arcade）の中だけに効く。ほかのページには影響しない。
   - 夜のカードテーブル：金のふちのカード裏・3Dでめくる・レアはホロ・コンボ・星3つ評価。
   - 絵文字を UI の記号に使わない（アイコンは assets/img/cardgames/icons/ と インラインSVG）。
   - スマホ縦持ち最優先（押す所は 44px 以上）・prefers-reduced-motion 対応。
