/* RPX 홈페이지 스타일
   구성: 1 토큰 · 2 기본 · 3 공통 조각 · 4 헤더 · 5 홈 · 6 본문 페이지 · 7 푸터 · 8 영어 화면 · 9 움직임 · 10 좁은 화면

   디자인 규칙(2026-10-08, taste-skill 점검 뒤 정한 것. 고칠 때 지킬 것):
   - 색: 차가운 회색 한 계열 + 강조색은 로고 빨강 하나. 브랜드 색(RADIDERM 파랑)은 그 브랜드 페이지 안에서만.
   - 화면은 밝은 테마 하나. 중간에 검은 구역을 끼우지 않는다(푸터 제외). 강조 구역은 한 단계 어두운 회색(--bg-2).
   - 모서리는 전부 각지게. 버튼만 2px.
   - 구역 제목 위에 작은 번호·영문 꼬리표를 붙이지 않는다. 장식용 점·선·캡션도 넣지 않는다.
   - 같은 모양의 카드 세 개를 나란히 놓지 않는다. 구역마다 배치를 다르게 쓴다.
   - 글꼴: 영문·숫자는 Geist, 한글은 Pretendard. 고정폭 글꼴은 쓰지 않는다(숫자는 tabular-nums). */
