## 2026-07-10 - Remove unnecessary DOMPurify for performance
**Learning:** 애플리케이션이 `textContent`와 같은 안전한 DOM API만 사용하고 `innerHTML` 등의 위험한 싱크를 사용하지 않는다면 DOMPurify와 같은 라이브러리를 통해 Trusted Types 정책을 생성할 필요가 없음.
**Action:** 불필요한 번들 다운로드 및 스크립트 실행을 방지하기 위해 사용하지 않는 라이브러리를 식별하고 제거할 것.

## 2024-07-22 - SVG 및 LCP 이미지에 대한 decoding="async" 지연 성능 이슈
**Learning:** SVG 이미지나 LCP(Largest Contentful Paint)에 중요한 이미지에 `decoding="async"` 속성을 부여하면 브라우저의 렌더링이 지연되어 오히려 초기 화면 표시 성능이 저하될 수 있습니다.
**Action:** SVG나 중요 렌더링 경로에 있는 이미지에는 `decoding="async"`를 제거하여 성능을 최적화합니다.
