   # 왜 xerost.css / soulie.css 를 쓰지 않나

   호스트마다 브랜드가 다르고 파일은 한 페이지에 하나만 로드된다. si 는
   옛 si 사이트와 2026-09 소개서가 쓰던 검정 + 파랑(#00A8FF)이다 — 소개서와
   사이트가 같은 얼굴이어야 한다.

   # 구조는 soulie.css 와 같다

   site.js / contact.js 가 기대하는 상태 클래스(.header.is-stuck,
   .nav__link.is-active, .burger.is-open, .mobile-nav.is-open,
   [data-reveal].is-in, .form__msg.is-*, .spinner)를 그대로 쓴다.

   # 이 저장소에서 겪은 함정을 반영한 규칙

   - `[hidden]` 을 컴포넌트 display 가 이긴다 → !important 로 눌러둔다
   - 장식용 절대배치가 문서 폭을 넓힌다 → .section/.hero 에 overflow: clip
   - 한글은 word-break: keep-all 이 없으면 단어 중간에서 잘린다
   - 미디어쿼리를 먼저 쓰고 같은 선택자를 뒤에 또 쓰면 뒤가 이긴다
   - 100vw 는 부모 여백을 모른다 → 폭은 100% 로
