/* ============================================================
   VTCC Admin Design System — 2026 라이트 리프레시
   공개 챗 위젯(chat-widget.css)과 같은 제품군: 바이올렛→인디고 그라디언트
   (#7C3AED → #4F46E5), 클린 뉴트럴 서피스, 레이어드 소프트 섀도.

   주의: 다른 admin 템플릿들이 아래 CSS 변수와 클래스명을 인라인
   스타일에서 직접 참조합니다. 변수/클래스 이름은 절대 변경하지 말 것.
   (값 튜닝은 허용, 추가는 자유)

   목차
     00. 프리로드/폰트 로딩 가드
     01. 디자인 토큰 (:root) + 다크 테마 자리([data-theme="dark"])
     02. 베이스 리셋 · 스크롤바 · 포커스 · 선택영역
     03. 레이아웃 셸 (.layout / .sidebar / .main / .adm-topbar / .adm-content)
     04. 사이드바 내비게이션 (+ collapsed)
     05. 레거시 공유 컴포넌트 (page-header, card, btn, form, table,
         tag, stats, alert, spinner, empty-state …) — 이름 유지, 값 재조정
     06. 공유 이름 보강 (modal-overlay, badge, pagination, form-hint,
         upload-area/zone, progress-bar) — 페이지 인라인 중복 삭제 가능
     07. adm-* 컴포넌트 라이브러리 (신규)
     08. 유틸리티
     09. 반응형
     10. 모션 감소
