 * assets/css/tool-image-compress.css - [이미지 용량 줄이기] 전용 격리 스타일시트
 * ============================================================================
 * [디자인 특징]
 * 1. 스크린샷 100% 일치 가로형 리스트 레이아웃 (썸네일 | 파일명+포맷+원본크기 | 절감률+압축크기 | 다운로드 버튼)
 * 2. 통일된 디자인 시스템: Pretendard 폰트, 보라색(#8b5cf6)/블루(#3b82f6) 포인트, 일관된 라운딩 및 그림자
 * 3. 전체 압축 통계 카드: 총 원본 용량, 총 압축 용량, 총 절감량 요약 대시보드
 * 4. 반응형 레이아웃: 모바일과 데스크톱 모두 쾌적한 사용성 제공
