/* insights.v4.css (v4_3 재질 번역: insights 허브 + posts 3, course.v4.css 위 오버레이. 셀렉터/골격/브레이크포인트 원본 보존)
   1) build/tokens.css 임포트 삭제. 본 파일 내 --iruri-* 사용 0건이라 인라인화 대상 없음. 로컬 루트 변수블록 제거, 전부 site.v4.css 토큰 직치환 (dead var: --navy, --serif 미사용이라 폐기)
   2) radius/shadow/hover translateY 제거, 심도는 plate 카드판 + hair/hairsoft 헤어라인. 알약 CTA 2종은 0-radius 헤어라인 버튼(hover만 foil 채움)으로
   3) 장문 가독: 본문 p/목록 muted에서 ink로 승격, 인용/메타만 muted, 본문 링크 goldline 밑줄 룰 신설(원본에 본문 a 룰 부재, 파운데이션 전역 no-underline이라 링크 식별 불가 버그 보강). blockquote 한글 합성 이탤릭은 normal로
   4) focus-visible(본문 링크) + prefers-reduced-motion 가드 추가. 섹션 리듬: post-hero plate, post-body field 상속, post-footer deep2 침강 */
