   image.css — TimeSave Image 서비스 스타일
   ------------------------------------------------------------
   공통 디자인 토큰은 pdf/link 와 동일 계열을 따르되,
   image 서비스 액센트만 lime(#65A30D)로 교체한다.
   레이아웃은 image.md 확정 설계:
     · 데스크톱: 좌(이미지 전/후 위아래) | 우(아코디언 + 이력)
     · 모바일:   카드 → 이미지(전/후 좌우) → 아코디언 세로 스택
   처리 모델: 적용 기반 파이프라인(원본 + 적용 작업 목록) + 되돌리기.
