+## 2024-07-12 - DateRangePicker 토글 버튼의 키보드 접근성 및 상태 인지 개선
+**Learning:** 여러 선택지 중 하나를 고르는 토글 형태의 버튼 그룹(예: 기간 선택 프리셋)에서는 시각적인 스타일(색상) 변화만으로 상태를 나타내면 스크린 리더 등 보조 기기 사용자가 현재 선택된 값을 인지하기 어렵습니다. 또한 키보드 네비게이션 시 포커스 링(`focus-visible` 클래스)이 빠져 있으면 사용자가 어떤 버튼에 위치해 있는지 시각적으로 확인하기 어렵습니다.
+**Action:** 토글 형태의 버튼이나 탭에는 반드시 `aria-pressed={isActive}` 속성을 추가하여 상태를 명확히 전달하고, Tailwind CSS를 사용할 때는 `focus-visible:outline-none focus-visible:ring-2`와 같은 키보드 포커스 스타일을 반드시 포함하여 키보드 접근성을 확보해야 합니다.
