/* =============================================================================
 *  LAON 대시보드 스타일 (2026-09-18 새 단장)
 *
 *  설계 §2.1 - 색만으로 상태를 구분하지 않는다. 아이콘 + 텍스트를 항상 같이 쓴다.
 *             (적록색약이 남성 20명 중 1명이다. 배터리 현장에 반드시 있다)
 *
 *  ★ 토큰으로만 색을 쓴다. 라이트/다크가 :root 한 곳에서 갈린다.
 *    - 상태색(ok/warn/fault/danger/off/nobms)은 **상태에만** 쓴다. 그래프 시리즈에
 *      쓰지 않는다 (dataviz: 상태색은 예약).
 *    - 강조색(accent)은 그래프 시리즈 1(파랑)과 같은 계열이라 브랜드가 한 결로 읽힌다.
 *  ★ 외부 CDN 없음 (폐쇄망 고객사). 폰트는 설치돼 있으면 Pretendard, 아니면 시스템.
