/**
 * v7/post/popular.css - 인기 게시글 목록 페이지 스타일
 *
 * v7 전용 CSS. Bootstrap 미사용.
 *
 * 디자인 원칙:
 *   - 텍스트는 가독성을 위해 어두운 색을 직접 지정 (#0f172a, #334155, #64748b)
 *   - 보더는 옅은 회색으로 부드럽게 (#e2e8f0, #f1f5f9)
 *   - 호버 시 배경/보더만 살짝 변경, 텍스트 색은 브랜드 컬러로 강조
 *   - WA 변수 fallback이 의도한 색상과 다르게 적용되는 문제를 피하기 위해
 *     주요 색상은 모두 직접 지정한다.
