🎨 Palette: 토스트 알림 및 상태 메시지 접근성 개선

[seonghobae]

💡 무엇을

• index.html 내의 동적 알림 요소(<div id="toast">, <span id="sync-status">)에 role="status"와 aria-atomic="true" 속성을 추가했습니다.
• .jules/palette.md 파일에 이번 접근성 개선 작업을 통해 배운 내용을 기록했습니다.

🎯 왜

• aria-live="polite"만 사용하는 경우 스크린 리더는 요소 내 텍스트의 변경된 부분만 읽거나, 구현체에 따라 전혀 읽지 않는 등 동작이 일관되지 않을 수 있습니다.
• 상태 메시지(status messages)의 경우 전체 내용을 읽어주어야 사용자에게 명확한 맥락(예: '프로젝트가 저장되었습니다')을 제공할 수 있으므로, role="status"와 내용 전체를 하나의 덩어리로 묶는 aria-atomic="true"를 명시적으로 추가하여 접근성을 높이고자 했습니다.

📸 변경 전/후

• 시각적인 변경(UI 변화)은 없으며, DOM의 속성만 변경되었습니다.

♿ 접근성

• 보조 기술(스크린 리더) 사용자가 화면 내 알림이나 동기화 상태 변경(예: "브라우저 로컬 자동저장 사용 중")과 같은 동적인 상태 메시지를 보다 명확하고 완전하게 전달받을 수 있도록 개선했습니다.

👋 Jules, reporting for duty! I'm here to lend a hand with this pull request.

When you start a review, I'll add a 👀 emoji to each comment to let you know I've read it. I'll focus on feedback directed at me and will do my best to stay out of conversations between you and other bots or reviewers to keep the noise down.

I'll push a commit with your requested changes shortly after. Please note there might be a delay between these steps, but rest assured I'm on the job!

For more direct control, you can switch me to Reactive Mode. When this mode is on, I will only act on comments where you specifically mention me with @jules. You can find this option in the Pull Request section of your global Jules UI settings. You can always switch back!

Warning

Review limit reached

@seonghobae, you've reached your PR review limit, so we couldn't start this review.

Next review available in: 44 minutes

Limit details: You’ve used all 1 included review currently available under your plan.

You've used all free OSS reviews for now. Wait for the free limit to reset to keep reviewing this public repository.

How can I continue?

After more reviews become available, a review can be triggered using the @coderabbitai review command as a PR comment. Alternatively, push new commits to this PR.

To avoid repeated limits, reduce automatic review volume by pausing incremental auto-reviews earlier, using label-based review opt-in, excluding WIP or generated PR titles, or requesting reviews manually when the PR is ready. If your team needs uninterrupted high-volume reviews, an organization admin can enable usage-based reviews.

How do review limits work?

CodeRabbit enforces per-developer PR review limits for each organization. Most developers receive the normal plan review availability.

For paid Pro and Pro+ PR reviews, CodeRabbit uses adaptive limits for sustained high-volume activity. When a developer's recent PR review activity reaches the 95th percentile or higher among CodeRabbit users, additional reviews become available more gradually as earlier reviews age out of the rolling window.

Please refer docs for additional details.

Superseded by the existing canonical accessibility lane in #491. The only unique product delta here—explicit role="status" on the already-polite/atomic #sync-status region—has been preserved there test-first (0befe87f2e... regression, then 20f6088225... production markup) alongside the stronger toast visibility/browser acceptance contract. The #toast semantic change was already present in #491. The generated .jules/palette.md journal is not required product/runtime evidence and is intentionally not duplicated. Closing this parallel PR avoids overlapping index.html writers while preserving the valuable behavior in one reviewed branch.

Understood. Acknowledging that this work is superseded by #491 and the PR is closed as obsolete. Stopping work on this task.
