  글로벌 약사 크리에이터 아카데미 — 스타일시트 (7개 파일을 하나로 합친 것)

  ▸ 읽는 법
    위에서 아래로 적용됩니다. 같은 요소에 규칙이 여럿이면 "아래쪽 규칙"이 이깁니다.
    그래서 최신 수정은 파일 끝부분(7번 구역 끝)에 있습니다. 값을 바꿀 때는 끝에서부터 찾으세요.

  ▸ 구역
    1. 기본        2. 본문 레이아웃        3. 헤더·목차·상세창·하단 지원 바
    4. 수치 카드    5. 브랜드 로고 흐름     6. 사진 위 손글씨 표시        7. 개편(v2) 규칙

  ▸ 자주 고치는 곳 (Ctrl+F 검색어)
    - 섹션 색 5가지(네이비·파랑·로고 파랑·연파랑·연회색) ........ "--c-navy"
    - 섹션별 배경 순서(어느 섹션을 칠할지) ....................... "PM_ v3"
    - 섹션 머리 색 띠 ........................................... ".sec-head"
    - 글자 크기·굵기 체계(제목 38 / 본문 18 / 카드 16 / 설명 13) ... "one type system"
    - 사진 크기·비율·모서리 .................................... "one image format"
    - PC 하단 지원 박스 ......................................... "desktop-cta"
    - 모바일 전용 규칙 .......................................... "@media (max-width: 800px)"

  ▸ 일정(모집 마감·개강 등 날짜)은 CSS가 아니라 schedule.js에서 고칩니다.
