   1. OrganicLoader  — 모핑 블롭 (size 의존 keyframe만 인라인 유지)
   2. GlobeLoader    — 회전 와이어프레임 globe
   3. CosmicScale    — 동심원 스캐너
   4. CalcKey        — 두께감 있는 계산기 키
   5. PulseBars      — 이퀄라이저 (LIVE / 미니 플레이어)
   6. Aurora         — 슬로우 드리프팅 백그라운드

   글로벌 keyframes (cp-pulse, cp-eq, cp-drift1~3, cp-globe-spin,
   cp-city-pulse, cp-cosmic-ring) → app.css에 정의.
