/**
 * @file sfImageSanitizer.css
 * @description sfImageSanitizer 애플리케이션의 모든 시각적 스타일을 정의하는 CSS 파일입니다.
 *
 * [핵심 디자인 철학]
 * - 네임스페이스(Namespace): 모든 클래스에 'sfImageSanitizer-' 접두사를 사용하여,
 *   다른 CSS 라이브러리나 웹사이트의 기존 스타일과 충돌하는 것을 원천적으로 방지합니다.
 * - 독립성/이식성: body 태그에 영향을 주지 않아, 어떤 웹페이지에 삽입되어도 자연스럽게 어우러집니다.
 * - 다크 테마(Dark Theme): 전반적으로 어두운 계열의 색상을 사용하여 전문적인 분석 도구의 느낌을 줍니다.
