   PubStation · Classic Editorial Design System
   버전: v7.5.0 (Phase 1 초안)
   출처: data/output/design/aipublisher_design_handoff_package/
   구성:
     1. 폰트 선언 (@font-face, @import)
     2. 토큰 (--pub-*) + 기존 토큰 재정의
     3. 기본 리셋 + 타이포 + 레이아웃
     4. 공통 컴포넌트 (site-header, nav, button, panel, form, eyebrow,
        check-list, photo-frame, glass-card, step, output-card, content-card,
        price-card, faq, final-cta, site-footer)
     5. 반응형 (1024px, 720px, 480px)
     6. 접근성 (prefers-reduced-motion)
     7. Bootstrap Cascade Overrides
   Phase 1 원칙:
     - 기존 HTML 마크업 수정 없이도 editorial 톤이 적용되도록 Bootstrap 오버라이드 포함
     - 기존 5개 CSS(`design-system.css`, `modern-ui.css`, `navbar.css`, `style.css`,
       `fonts.css`)와 공존 가능해야 함. editorial.css가 더 강한 cascade를 갖도록 순서 주의.
     - 아직 base.html과 연결 안 됨. Phase 2에서 link.

/* Noto Serif KR (헤드라인 한글 명조) — 로컬 Variable Font
 * v7.5.0 P1 Tier A 후속 수정 (2026-04-26):
 *  - 이전 NotoSerifKR-Variable.ttf 파일이 절단(7.4MB / 정상 23.8MB)되어
 *    Chromium "OTS parsing error: BASE: invalid table offset" 발생.
 *    notofonts/noto-cjk 공식 Variable TTF로 교체 + format() 표준화.
 *  - format("truetype-variations")는 webkit 비표준 토큰. Chromium은 동일
 *    파일을 인식하지만 Variable Font 테크 힌트는 별도 `tech("variations")`
 *    Level 4 문법으로 분리하는 것이 안전.  현재 호환성 우선 → 둘 다 명시.
