/* ==================================================
   GLINS PRODUCT DETAIL STYLES
   제품 상세 페이지(detail_*.html)의 공통 스타일.
   히어로 · 필터바 · 제품 카드 그리드 · 스펙 비교표 · CTA.

   반드시 common.css '뒤에' 로드할 것 (.product-section 등 일부
   클래스가 common.css와 겹치므로 이 파일이 나중에 와서 이겨야 함).
       <link rel="stylesheet" href="assets/common.css">
       <link rel="stylesheet" href="assets/detail.css">

   히어로 래퍼는 .detail-hero 클래스를 사용한다.
