   ⚠️ tokens.css / components.css는 더 이상 @import하지 않는다.
   CSS @import 대상 URL은 build_templates.py의 캐시 버스팅(?v=...)이 닿지 않아
   Cloudflare 엣지/브라우저에 최대 7일(+30일 stale-while-revalidate) 그대로
   캐시되며, 매 배포마다 새로 붙는 <link>의 tokens.css를 소스 순서상 뒤에서
   재정의해 무효화시키는 사고까지 발생했다(2026-09-04). 두 파일 모두
   head_common.html에 tokens.css → components.css → style.css 순서의 <link>로
   직접 연결해 동일한 캐시 버스팅 쿼리스트링을 받도록 한다. 절대 되돌리지 말 것.

   12. Footer
   [§2.4 CSS_JS_COMMONIZATION_REFACTOR_PLAN.md] .site-footer의 실제 렌더링 정의는
   legal_modal.css(로딩 순서상 항상 승리)에 있고, 그 파일이 나머지 3-Tier 푸터
   서브 컴포넌트(.footer-top-grid/.footer-brand-col/.footer-bottom-bar 등)까지
   전부 소유하는 구조라 이 파일의 .site-footer 정의는 도달 불가 데드코드였다.
   푸터 컴포넌트 전체를 쪼개서 옮기는 대신 legal_modal.css를 그대로 단일 소유자로
   유지하고 이 파일의 중복 정의만 삭제했다(시각적 변경 없음, legal_modal.css:9 참고).
