/* 공지사항 스킨 v3 — 입체 카드 + 에디토리얼 리딩 (2026-08-01)
 *
 * 입체감 체계
 *  · 표면: 카드에 미세한 상단광 그라데이션(위가 살짝 밝음) → 종이가 아니라 '패널'로 읽힘
 *  · 그림자 3층: ①윤곽(1px 근접) ②중간(6~10px) ③환경광(24~40px, 아주 옅게)
 *  · 아이콘 타일: 카테고리색 그라데이션 + 안쪽 하이라이트 + 타일 자체 그림자 = 떠 있는 버튼감
 *  · 페이지 배경에 옅은 라디얼 글로우 → 흰 카드가 배경에서 분리되어 떠 보임
 *  · 호버: 3px 리프트 + 그림자 심화 + 화살표 슬라이드 (누를 수 있다는 어포던스)
