 * 그누보드5 격리 | BEM | 모바일 퍼스트
 *
 * 기존과 구별:
 * - tips388: Cobalt Blue #1d4ed8 blue-700 (짙은 남색/코발트, 딥 사파이어 느낌)
 * - tips394: Sky Blue #0ea5e9 sky-500 (하늘색/시원한 하이라이트)
 * - tips401: Neural Blue #3b82f6 blue-500 ("전기 파랑"·진짜 Royal Blue)
 *   → 더 선명하고 "AI·데이터·신경망" 느낌, 중간 밝기 블루
 *   → base #050a14 (더 어두운 네이비-블랙)
