/* ============================================================
   el_unified — 통합 사이트 테마 v0.1
   기반: el_gate(eondui 토큰 브리지 + supporterb 구조) 위에
        el_imweb의 상호작용 메커니즘(이중 내비·스티키 탭·카드그리드·
        FAQ 아코디언·스크롤 리빌)을 스킨만 교체해 이식.
   원칙: el_imweb은 imweb.me "클레이" 색(그린 #008C00 등)을 그대로 썼지만,
        여기서는 그 색 이름 대신 --e-* (eondui) 값을 참조한다 — 새 색을
        만들지 않고 기존 --un-* 변수의 "의미"만 유지한 채 값을 스왑.
   프리픽스: un- (unified). 이 파일은 항상 eondui.css보다 뒤에 로드.
