 ## 2026-08-08 - 애니메이션 성능을 위해 top/left 대신 transform 사용
 **Learning:** 이 skip-link 전환을 `top`에서 `transform`으로 바꾸면 애니메이션 중 레이아웃 재계산을 피하는 데 유리합니다. 개발자 도구에서 이 전환의 Layout 이벤트가 관찰되지 않았지만, 브라우저·장치별 GPU 가속이나 메인 스레드 비용 0ms를 보장하지는 않습니다.
 **Action:** 레이아웃 속성 대신 `transform` 전환을 우선 검토하고, 성능 효과는 브라우저별 측정으로 확인하며 절대적인 GPU·비용 보장으로 기록하지 않습니다.
+
+## 2024-09-16 - lazy 이미지에 fetchpriority="low" 적용하여 성능 최적화
+**Learning:** `loading="lazy"`가 적용된 오프스크린 이미지라도 브라우저가 파싱 시점에 리소스 우선순위를 명확히 알 수 있도록 `fetchpriority="low"`를 추가하면, 메인 스레드 렌더링 경로의 핵심 리소스(예: LCP 후보)에 네트워크 자원을 더 집중하게 할 수 있습니다.
+**Action:** 지연 로드되는 이미지에는 항상 `fetchpriority="low"`를 함께 지정하여 브라우저의 리소스 가져오기 우선순위를 명시적으로 낮춥니다.
