🎨 Palette: [UX improvement] Add title to icon-only buttons

[seonghobae]

아이콘 전용 버튼에 aria-label과 동일한 title 속성을 추가하여 마우스 사용자에게 네이티브 툴팁을 제공하는 UX/접근성 개선 PR입니다.

💡 What

• ScoreViewer의 확대, 축소, 이전 페이지, 다음 페이지 아이콘 버튼에 title 속성 추가
• ScoreView의 첨부파일 삭제 아이콘 버튼에 title 속성 추가
• 테스트 코드에서 title 속성이 정상적으로 렌더링되는지 검증 추가
• .jules/palette.md 파일에 이번 학습 및 개선 사항 기록

🎯 Why

아이콘 전용 버튼의 경우 aria-label이 있어 스크린 리더 사용자는 버튼의 역할을 알 수 있지만, 일반적인 마우스 사용자는 툴팁 없이 아이콘만으로 기능을 추론해야 하는 불편함이 있었습니다. title 속성을 추가하면 마우스 호버 시 브라우저 기본 툴팁이 나타나 직관적인 UX를 제공할 수 있습니다.

♿ Accessibility

시각 장애인을 위한 스크린 리더 지원(aria-label)과 시력이 정상인 마우스 사용자를 위한 툴팁(title)의 정보를 일치시켜 일관된 접근성을 제공합니다.

👋 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: 12 minutes

Limit details: You’ve used the included review currently available.

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 within each organization.

For paid Pro and Pro+ reviews, CodeRabbit uses a developer's included PR review attempts over the past 7 days to set the current hourly allowance. At typical activity levels, the full plan allowance applies. Higher sustained activity can lower the allowance until earlier attempts leave the 7-day window.

Please refer docs for additional details.

Pull request overview

OpenCode cannot approve yet because required coverage evidence did not pass.

Review outcome

1. HIGH .github/workflows/opencode-review.yml:1 - Coverage evidence did not prove required test/docstring evidence

• Problem: The required coverage-evidence job result was failure, so OpenCode cannot establish approval sufficiency for this head.

• Root cause: Automated approval is only valid when the same-head coverage-evidence job proves supported repository test suites passed and configured docstring gates passed or were advisory, or reports not applicable because no supported source files or package manifests exist. Missing, failed, skipped, unavailable, or unsupported-tooling test evidence is a blocker.

• Fix: Install or configure the repository test/docstring evidence tooling when source files or package manifests exist, rerun the current-head coverage-evidence job, and approve only after it reports success with required evidence or explicit no-source not-applicable evidence.

• Regression test: Keep the approval branch checking needs.coverage-evidence.result == success before posting APPROVE, and publish REQUEST_CHANGES when coverage-evidence blocker states such as cancelled, skipped, failed, unsupported-tooling, or below-100 evidence are present.

• Result: REQUEST_CHANGES

• Reason: coverage-evidence result was failure, so required test/docstring evidence was not proven for current head a48ba50fed6fa79b325d9fce90e8f746f135ae54.

• Head SHA: a48ba50fed6fa79b325d9fce90e8f746f135ae54

Closing as a proven superseded duplicate of canonical accessibility PR #731. Fresh exact-head comparison against #7318388b9c shows #731 already carries every buyer-visible behavior in #938a48ba50: localized native titles for ScoreViewer zoom and previous/next controls, plus file-specific ScoreView remove titles. #731 additionally covers fit-width, enabled Open tooltips, unavailable-state recovery copy, renderer-owned aria-describedby targets, keyboard-focusable aria-disabled pagination/removal, guarded no-op activation, localized regressions, CHANGELOG, and doctoring. #938's only non-product delta outside those same source/tests is .jules/palette.md, which is not unique runtime behavior or release evidence worth maintaining as a competing writer. No #938-only product contract needs preservation.
