/*
  Zenith site — shared stylesheet.
  Design system: "quiet trust" (V2 base: stone paper + single deep green
  accent, dark rounded panels) blended with V1's editorial warmth (numbered
  index marks, pull-quote block, thin-rule eyebrow labels).
  Single accent color only (design_audit A2.3). No pure black (A2.1).

  2026-07-17 모션 업그레이드(UPGRADE_SPEC.md 기법 A/B/D/E/F) 추가:
  - E. View Transitions — 페이지 전환 시 네이티브 크로스페이드(0KB, 라이브러리 없음).
  - A. 유동 대형 타이포 — .headline/.entries-h/.problem-h/.final-h/.page-h/.how-h.
  - B. 스크롤 리빌 가드 — .reveal 기본값은 항상 opacity:1(캡처 안전). .js-anim이
    JS 성공 시에만 붙어서 그때만 opacity:0 초기 상태로 들어간다.
  - F. 다크 패널 메탈릭 시트 + 스탯/사업라인 카드 3D 틸트(motion.js에서 처리).
