/* ============================================================
   st02a(마스터) 슬롯 게임목록 팝업(#gamePopup) 스타일 — 라이트/레드 테마.
   구조는 STX _GamePopup 계약(game.js renderGameList 출력)과 동일:
     .game-popup > .game-popup-inner > .game-popup-header(title+close)
       + .game-popup-body(.game-popup-loading + ul.game-popup-list > li(img + .game-name + .game-hover>.play-icon))
   프리마(다크/금색) 구조를 이식하되 st02a 라이트(#fff 패널) + 레드(#cc2124) 액센트로 재테마.
   🔴 토큰(var(--earth-*)/--z-*) 의존 제거(st02a 미정의) — 명시 색상/명시 z-index(로그인 50000 위 50001).
