       ============================================================
       주의: 관리자 쪽 app.css가 이미 --lh-primary/--lh-bg-cream/--lh-surface를
       거의 동일한 값으로 전역 :root에 정의해 두고 있지만 --lh-border/--lh-text-*는
       값이 다르다(회원 포털 목업이 더 밝은 톤으로 확정). 여기서 :root에 다시 선언하면
       나중에 로드되는 이 스타일시트가 이겨서 관리자 화면까지 색이 바뀌므로, 반드시
       .member-portal-scope 아래에서만 토큰을 재정의한다(MemberLayout.razor의 최상위
       래퍼에 이 클래스를 건다). */
