/* game-arena.css — Kanji Arena "võ đường ban đêm" (templates/pages/games/kanji_arena.html + arena/_play.html +
   arena/_result.html). Bản vẽ đã duyệt: KA_Play (máy tính), KA_Input, KA_Battle, KA_Result, KA_Mobile.
   Mình = cam, đối thủ = xanh, vàng = combo. Chữ Hán trên "thẻ giấy" dùng Shippori Mincho B1, số dùng Chakra Petch.
   Game có bảng màu riêng (bản vẽ) → khai báo MỘT chỗ ở đầu file (--ka-*), đồng thời đổi các biến chung của
   tokens.css trong phạm vi trang để nút/nhãn/hộp thoại dùng chung (btn, tag, callout, toast, dialog) tự thành nền tối.
   Bố cục: ≥1200px ba cột (thẻ | bàn 3×2 | thẻ) · 600–1199px thẻ ở trên, bàn 3×2 · <600px (điện thoại dọc) thẻ nhỏ
   2 cột + thanh lượt + bàn 2×3 · cao ≤520px (điện thoại ngang) thẻ bên trái, bàn 3×2 bên phải. */
