/**
 * 파일명: assets/css/gift-ranking.css
 * 위치: /assets/css/
 * 기능: 판촉물 인기 순위(gift_ranking.php) 전용 스타일
 *
 * @version   1.2.0
 * @updated   2026-07-27
 * @standalone 원천 고유 디자인이다 — panchok/zengift 로 복사하지 않는다.
 *             팔레트 출처: ~/OneDrive/WEB/Projects/docs/design/design_system_03-dark-mono-clean.md
 *             허브·홈·세부 카테고리와 같은 팔레트·같은 컴포넌트 패턴을 재사용한다.
 * @changelog
 *   1.2.0 (2026-07-27) 히어로 빠른 메뉴(.rank-nav-link) 추가 — 마지막 업데이트 배지 옆
 *   1.1.0 (2026-07-27) FAQ 복원에 맞춰 .rank-faq-item 아코디언 스타일 추가(허브 .hub-faq-item 과 동일 패턴)
 *   1.0.0 (2026-07-27) 최초 작성 — 4단계 2차 본작업 마지막 페이지: 순위 화면 독자 디자인.
 *                      순위 뱃지(금·은·동)는 그라데이션 대신 테두리 색만 다르게 하는 방식으로
 *                      단순화(DS03 "그라데이션 없음" 원칙). 사용하지 않던 .stats-card 계열
 *                      (마크업에서 참조된 적 없음) 은 이식하지 않았다.
