/* ============================================================
 * ⚔️ ĐẤU XẾP HẠNG 24G — rank.css  ·  PREMIUM GAME UI (S55, 24/08)
 * ============================================================
 * Chỉ chứa class có tiền tố .g24-rank-* / .rk-* / .g24-lb* → KHÔNG
 * đè lên style cũ của g24.css. Nạp SAU g24.css trong index.html.
 * Mọi màu lấy từ tokens.css (đỏ #E60012 + vàng kim + trắng kem).
 *
 * NGUYÊN TẮC (anh Tiền chốt 24/08):
 *   · Cảm giác "app game cao cấp", KHÔNG phải trang web vài nút đỏ.
 *   · Bo góc lớn · viền tinh tế · bóng nhiều lớp · highlight phản chiếu.
 *   · Animation chỉ chạy trên transform/opacity (mượt trên điện thoại),
 *     và TẮT SẠCH khi máy bật "giảm chuyển động".
 *   · Vùng chạm ≥ 48px. Không tràn ngang. Không bị bottom nav che.
 * ============================================================ */
