 * 테마: 엠버 코퍼 #ea580c (orange-600) + 딥 엠버 다크 #0c0300
 *      (보안 경고·차단·제한·Rust·Lock 연상)
 * 그누보드5 격리 | BEM | 모바일 퍼스트

 * 기존과 구별:
 * - tips390: orange-500 #f97316 (밝은 네온 오렌지)
 * - tips397: amber-400 #fbbf24 (골드 옐로우)
 * - tips400: amber-500 #f59e0b (옐로우 앰버)
 * - tips404: orange-600 #ea580c ("경보 구리·번트 코퍼", 보안 경고 색상)
 *   → 더 짙고 붉은 오렌지, "차단·경고·제한" 느낌에 최적
 *   → base #0c0300 (코퍼/엠버 반영된 딥 러스트 블랙)
