                   · 네비게이션, 푸터, 주요 제목, 로고
     --secondary : 정보·안내 / 부가 콘텐츠 / 링크 (블루)
                   · 본문 링크, 안내 배지, 보조 카드 헤더
     --accent    : 액션 / 상담 신청 / 중요 강조 (코랄)
                   · CTA 버튼, 주목 수치, 긴급 알림
     --growth    : 데이터 / 근거 / 과학적 수치 (틸)
                   · 통계, 효과 크기, 연구 인용, 성장 지표
