/* ============================================
   NOVA CASINO — 컨셉 테마 파일 (활성: STORM / 번개)
   ------------------------------------------------
   ■ 컨셉 교체 방법: 이 파일(theme.css)과 assets/images/fx/ 의 3개 이미지를 같은 이름으로 바꿔 끼우면 끝.
      - fx-left.svg  : 좌측 큰 이펙트 (세로형, 320×720 권장)
      - fx-right.svg : 우측 큰 이펙트
      - fx-icon.svg  : 섹션 제목·로고 포인트 아이콘 (24×24)
   ■ 이 파일이 덮어쓰는 "이펙트 슬롯" (common.css / login.css 의 기본값은 SUPERNOVA):
      [공통]  body::before(배경 레이어1) body::after(배경 레이어2)
              .page__content > .container::before(상단 이펙트 L)  .page__content::after(이펙트 R)
              .footer::after(전체 섬광)  .section__title::before(제목 아이콘)  .hero(홈 히어로)
      [로그인] body.login-page::before/::after  .login-wrap::before/::after  .login-bg-overlay  .login-logo::after
   ■ 팔레트 변수는 common.css :root 그대로 사용. 여기서는 이펙트만 다룬다.
