/**
 * 파일명: assets/css/info-page.css
 * 위치: /assets/css/
 * 기능: 안내 6P(about·faq·terms·privacy·cookies·inquiry) 공용 셸(site_topbar.php·info_page.php) 스타일
 *
 * @version   1.3.0
 * @updated   2026-07-28
 * @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 카테고리·순위와 같은 팔레트를 재사용한다.
 * @changelog
 *   1.3.0 (2026-07-28) .info-callout.is-success 변형 추가 (cookies.php 의 "핵심 안내" 녹색 박스용)
 *   1.2.0 (2026-07-28) faq.php 전용 컴포넌트 추가 — 검색창(.info-search), 카테고리별
 *                      아코디언(.info-faq-cat, 부트스트랩 accordion 재도색), 도움말 박스
 *                      (.info-help), 카테고리 배지(.info-cat-links)
 *   1.1.0 (2026-07-27) .info-feature 정렬 수정(사용자 피드백) — 아이콘+제목을 .info-feature-head
 *                      로 묶어 왼쪽 정렬 한 줄로. 기존엔 아이콘/제목만 가운데, 체크리스트는
 *                      왼쪽이라 어긋나 보였다.
 *   1.0.0 (2026-07-27) 최초 작성 — 안내 6P 공용 셸 신설(4단계 잔여 작업).
