   NX ONLINE — Ultimate v1 (Stable Refactor)
   - 목적: "기능은 그대로" + 중복/패치 덩어리 정리 + 유지보수성 상승
   - 컬러: core.css tokens 사용
     --color-primary / --color-secondary / --color-accent / --color-highlight
     --c-ink / --c-ink-2 / --c-white / --color-bg
   - 브레이크포인트: 주 기준 1040/640 (단, 컴포넌트 특성상 900/820/768/720/520/860 유지)
   - 주의: 도킹(aside fixed) 로직은 JS가 책임. CSS는 "기본 흐름"만 보장.
