💡 What: <nav> 태그의 aria-label 속성을 aria-labelledby.visually-hidden 클래스가 적용된 <span> 요소로 교체했습니다.
🎯 Why: Chrome Translate와 같은 브라우저 번역 도구는 HTML 속성(attribute)인 aria-label을 번역하지 않는 경우가 많아, 다른 언어로 번역할 때 스크린 리더 사용자에게 원본 언어(예: 디렉토리 목록)로 읽히는 문제가 있었습니다. 화면에 보이지 않는 텍스트 요소를 사용하면 브라우저가 이를 번역 대상 텍스트로 인식하여 번역이 적용됩니다.
📸 Before/After: 시각적 변화 없음.
♿ Accessibility: 스크린 리더 사용자가 자동 번역된 페이지를 탐색할 때 네비게이션 라벨도 일관성 있게 번역된 언어로 들을 수 있습니다.

📝 Walkthrough

Walkthrough

탐색 영역의 aria-label을 제거하고 숨겨진 nav-label 요소를 추가했습니다. nav 요소는 aria-labelledby로 해당 요소를 참조합니다. 테스트와 접근성 문서도 새 마크업을 반영합니다.

Layer / File(s)Summary
숨겨진 탐색 레이블 적용
src/main/kotlin/html4tree/main.kt, src/test/kotlin/html4tree/MainTest.kt, .jules/palette.md
nav 요소가 aria-labelledby="nav-label"을 사용합니다. 테스트는 숨겨진 nav-label 요소와 해당 연결을 검증합니다. 문서는 번역 가능한 숨김 설명 텍스트 사용을 안내합니다.

Estimated code review effort: 1 (Trivial) | ~5 minutes

Merge Risk:🔵 Low · up to 7e286

This change replaces the navigation label attribute with translatable hidden text so browser-translated pages can expose translated navigation names to screen-reader users without visual changes. The bounded merge-readiness risks are an unresolved mismatch between repository guidance and the new markup contract, along with a documentation lint issue; both should have owner awareness or follow-up.

## 2026-08-17 - 브라우저 번역과 화면 판독기의 호환성을 위한 텍스트 처리
**Learning:** `aria-label` 속성으로 지정된 화면 판독기용 대체 텍스트는 Chrome Translate 등 브라우저 번역 도구에 의해 번역되지 않는 경우가 많습니다. 이로 인해 문서 언어가 변환되어도 스크린 리더에서는 원본 언어(예: 영어)로 읽혀 다국어 접근성이 저하됩니다.
**Action:** 화면 판독기를 위한 숨겨진 설명 텍스트를 제공할 때 `aria-label` 대신 CSS `.visually-hidden` 클래스를 적용한 `<span>` 요소를 사용하여, 브라우저가 일반 텍스트로 인식하고 번역할 수 있도록 하여 다국어 접근성 호환성을 확보하십시오.

🟡 Duplicate learning entry in palette log

The appended 2026-08-17 entry is byte-for-byte identical to the existing one directly above it, duplicating the same date and title. No blank line separates them, unlike every other entry in the file.

📝 Info: nav label switched from aria-label to aria-labelledby

CLAUDE.md documents a <nav aria-label> landmark. The nav now uses aria-labelledby referencing a visually-hidden span. The landmark keeps an accessible name, so the invariant holds; not flagged as a violation.

탐색 레이블 계약과 저장소 지침의 충돌을 해결하세요.

구현과 새 문서는 aria-labelledby 사용을 요구하지만, 저장소 코딩 지침은 <nav aria-label> landmark를 요구합니다. 승인된 계약을 하나로 정리한 뒤 코드와 문서를 같은 기준으로 수정하세요.

  • src/main/kotlin/html4tree/main.kt#L430-L431: aria-labelledby를 허용하도록 코딩 지침을 갱신하거나 <nav aria-label>을 사용하세요.
  • .jules/palette.md#L76-L78: 선택한 접근성 계약과 일치하도록 학습 항목을 수정하세요.

As per coding guidelines: "use a <nav aria-label> landmark."
