🎨 Palette: 빈 디렉토리 상태의 접근성 개선

[seonghobae]

💡 What: 빈 디렉토리 상태(<div class="empty-dir">)에 장식용 폴더 아이콘(📂)과 함께 role="status", aria-hidden="true" 속성을 추가하고, 해당 요소들이 수평으로 정렬되도록 .empty-dir CSS에 flexbox 속성을 적용했습니다.
🎯 Why: 스크린 리더 사용자가 볼 수 없는 빈 디렉토리에 접근했을 때 상태 변화를 즉각 인지할 수 있게 하고, 시각적으로도 빈 폴더라는 의미를 직관적으로 전달하기 위함입니다.
📸 Before/After: 시각적으로 기울임꼴 글꼴만 있던 기존 방식에서, 열린 폴더 아이콘이 추가되고 아이콘과 텍스트가 나란히 수평 정렬되는 방식으로 변경되었습니다.
♿ Accessibility: role="status"를 통해 보조 기기가 상태 메시지를 즉시 안내하게 하며, 장식용 이모지에는 aria-hidden="true"를 적용하여 불필요하게 소리내어 읽히지 않도록 개선했습니다.

빈 상태 마크업과 Flexbox 속성을 함께 검증해 주세요.

현재 aria-hidden="true" 검증은 상위 디렉토리 링크의 장식 아이콘만으로도 통과할 수 있어, 폴더 아이콘이 실제로 숨김 처리되었는지 보장하지 않습니다. 또한 새로 추가된 .empty-dir의 Flexbox 속성도 테스트되지 않습니다.

Closing as superseded by the protected base and draft canonical #360. The current generated empty state already includes aligned decorative treatment and status semantics. #360 owns the remaining tested visual readability and interaction contract after #363: explicit light/dark contrast, row separators, text-only hover/focus underline with full-target focus outline, reduced motion, browser regression, WCAG 2.2 doctoring, changelog, and fresh exact-head gates. No evidence from this duplicate head is reused.
