🎨 Palette: ContextSection 컴포넌트 키보드 및 스크린 리더 접근성 개선

[seonghobae]

💡 What

ContextSection 컴포넌트의 접근성을 향상시켰습니다. 펼침/접힘 토글 버튼과 내부 콘텐츠 요소 간의 관계를 스크린 리더가 명확히 인지할 수 있도록 useId()와 aria-controls 속성을 활용해 논리적으로 연결하고, 키보드 내비게이션 사용자(탭 키 이동)를 위한 시각적 포커스 피드백(focus-visible 스타일)을 추가했습니다.

🎯 Why

기존 구조에서는 버튼과 본문 영역 간의 관계가 명시되어 있지 않아 스크린 리더 사용자가 구조를 파악하기 어려웠으며, 마우스 hover 이외에 키보드 focus 상태를 보여주는 시각적 피드백이 누락되어 키보드 조작 사용성 결함이 있었습니다. 이 작업은 50줄 미만의 작은 변경으로 즉각적인 사용성 및 접근성 향상을 제공합니다.

📸 Before/After

로컬 환경에서 Playwright로 검증 시 탭 키 이동을 통해 토글 버튼에 명확한 포커스 링이 표시되며 원활하게 스페이스/엔터키로 조작되는 것을 확인했습니다.

♿ Accessibility

• useId를 사용한 고유 ID 생성
• <button>에 aria-controls 추가 및 콘텐츠 영역 id와 연결 (스크린 리더 지원)
• focus-visible 유틸리티를 적용하여 포커스 가시성 확보 (키보드 지원)

OpenCode Review Overview

• Head SHA: 5bede4728f1d0977529162d2e449e6536b7ddedb
• Workflow run: 28480192534
• Workflow attempt: 1
• Gate result: CHECK_FAILED (approval step)

Pull request overview

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

Check outcome

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

• Problem: The OpenCode approval path reached an APPROVE control result while the separate coverage-evidence job result was failure.

• 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, but leave the PR review unchanged for coverage-evidence blocker states such as cancelled, skipped, failed, unsupported-tooling, or below-100 evidence.

• Result: CHECK_FAILED

• Reason: coverage-evidence result was failure, so required test/docstring evidence was not proven for current head 5bede4728f1d0977529162d2e449e6536b7ddedb.

Closing as superseded during org-wide PR triage. Keeping #210 as the canonical PR for the same overlapping topic: ContextSection/accessibility accordion. This PR is stale/conflicted or has review blockers, so retaining one current PR reduces duplicated review and merge conflict work.
