/* =================================================================
   AI Studio — workstation-style layout (formerly Story Forge)
   -----------------------------------------------------------------
   레이아웃:
     [좌] Project sidebar  : 단계 navigator
     [중] Stage canvas     : 현재 단계 도구 (기존 forge step 들이 들어옴)
     [우] Asset drawer     : Cast / Voice catalog / Term base / Generated
     [하] Timeline         : NLE 스타일 V/A/Subs/BGM 트랙

   디자인 키:
     · 다크 슬레이트 베이스 + 그린 accent (#5cf2c0) 유지
     · 모서리 4px 만, 굵은 강조선 → DAW/NLE 톤
     · 라벨은 monospace + 약한 자간/대문자 — 워크스테이션 느낌
     · 카드/패널 간 1px solid 구분선만 — 그림자 최소화 (clean)
