/* =========================
   Public Header Dropdown SSOT (Ver.1349)
   - 공용 헤더 하위 메뉴는 공개 페이지와 홈피관리(/admin_panel)에서 같은 dark surface를 사용한다.
   - 페이지별 body/accent/surface token 또는 후순위 CSS가 메뉴 배경을 다시 light로 바꾸지 않도록
     public_layout/base의 header dropdown SSOT CSS로 로드한다.
   - MDN cascade/specificity 기준: 공용 컴포넌트는 한 파일에서 낮은 의존성으로 관리하고,
     페이지별 CSS보다 뒤에서 로드해 source order로 일관성을 확보한다.
