🎨 Palette: 시스템 폰트 및 레이아웃 개선으로 디렉토리 목록 가독성 향상

[seonghobae]

💡 What

생성된 index.html 파일에 다음의 기본 레이아웃 및 타이포그래피 CSS 스타일을 추가했습니다.

• body 태그에 system-ui 폰트, 적절한 line-height(1.5), 색상 및 패딩 추가.
• <main> 컨테이너에 max-width: 800px; margin: 0 auto;를 적용하여 라인 길이를 제한.

🎯 Why

디폴트 상태의 브라우저 폰트(보통 Times New Roman)와 전체 창 너비를 채우는 렌더링 방식은 넓은 스크린 환경에서 텍스트 줄글이 너무 길어지게 만들어, 사용자가 디렉토리 목록을 탐색(스캐닝)할 때 눈의 피로도를 높이고 가독성을 저해합니다. 기본적인 레이아웃 제약과 모던 폰트를 적용하면 이 문제를 손쉽게 해결할 수 있습니다.

📸 Before/After

Before:

• 전체 너비를 차지하며 엣지에 텍스트가 붙어있음.
• 브라우저 기본 세리프(Serif) 폰트로 렌더링.

After:

• 중앙 정렬된 최대 너비(800px) 컨테이너에서 깔끔하게 보여짐.
• OS 기본 산세리프(Sans-serif) 폰트가 적용되어 가독성이 상승함.

♿ Accessibility

• 글줄 길이가 너무 길어지지 않게 함으로써(Line length constraints), 인지/학습 장애가 있는 사용자나 저시력자가 리스트를 더 쉽게 훑어볼 수 있도록 돕습니다 (WCAG 관점에서의 리딩 개선).
• 더 나은 대비와 현대적인 타이포그래피로 전반적인 가시성을 향상했습니다.

✅ Verification

• ./gradlew test jacocoTestReport를 통해 변경된 CSS가 정상 출력되는지 검증하는 단위 테스트 추가 (MainTest.kt) 및 커버리지 100% 유지.
• .jules/palette.md에 관련된 UX 학습(레이아웃 제약을 통한 가독성 향상) 항목 추가.

OpenCode Review Overview

• Head SHA: d2010fa1861b9fb41eacc81b3b5badf94065b617
• Workflow run: 29151398251
• Workflow attempt: 1
• Gate result: REQUEST_CHANGES (approval step)

Pull request overview

OpenCode reviewed the current-head mergeability evidence and changed-file flow before approval, then found merge conflicts on the affected path.

Findings

1. HIGH Merge Conflict Guidance - Resolve the PR branch against the latest base branch

• Problem: GitHub reports mergeStateStatus DIRTY for this pull request.
• Root cause: Branch palette/typography-improvement-10280174232133268498 cannot be merged cleanly into master; the changed-file flow below shows which review/runtime path is blocked by the conflict.
• Fix: Merge or rebase the latest master into palette/typography-improvement-10280174232133268498, resolve conflict markers in the PR branch, rerun the focused checks, and push the same branch.
• Repair commands:

gh pr checkout 125 --repo ContextualWisdomLab/html4tree
git fetch origin master
git merge --no-ff origin/master  # or: git rebase origin/master
git status --short
# resolve files, then git add <resolved-files>
# merge path: git commit
# rebase path: git rebase --continue
git push origin HEAD:palette/typography-improvement-10280174232133268498
# rebase path only: git push --force-with-lease origin HEAD:palette/typography-improvement-10280174232133268498

• Regression test: Keep OpenCode approval gated on mergeability so model-output failures cannot approve a conflicted PR.
