/* ====================================================
   header-supplement.css
   레거시 whiteblue common.css 에 누락된 '데스크톱 기능 드롭다운'
   (.features-dropdown / .dropdown-grid 등) 스타일 보충.
   - common.css 에는 모바일 + .franchise-dropdown 데스크톱만 존재.
   - 디자인 의도(클릭 시 카드 그리드가 떠야 함)에 맞춰
     .franchise-dropdown 패턴 + 모바일 카드 토큰을 데스크톱으로 이식.
   - 769px 이상에서만 적용해 common.css 의 모바일 규칙과 충돌하지 않음.
