這個 PR 做了什麼

怎麼驗

檢查清單

• tool/check/commits.sh origin/main..HEAD 通過
  —— commit 訊息就是更新日誌，格式見 commit.md
• 一個 commit 一件事（這條 gate 驗不了，靠自己和 review）
• mise exec -- flutter analyze 與 mise exec -- flutter test 通過
• 新的使用者可見字串都走 AppLocalizations，沒有寫死
• CI 全部通過（gh pr checks：每一項都是 pass 或 skipped）—— 沒過不能合併，
  見 pr.md
• 有 UI 變更的話：用的是 AppSpacing / AppRadius / AppMotion，
  深色模式看過，文字對比度可接受
