ピョンと耳立て、言葉を直し
パスは年ごとにすっきりと並び
ロジックはそのまま、変わらぬ踊り
バッグに収めて、本日を刻む 🐇✨

There are 3 ways to chat with CodeRabbit:

• Review comments: Directly reply to a review comment made by CodeRabbit. Example:
  • I pushed a fix in commit <commit_id>, please review it.
  • Open a follow-up GitHub issue for this discussion.
• Files and specific lines of code (under the "Files changed" tab): Tag @coderabbitai in a new review comment at the desired location with your query.
• PR comments: Tag @coderabbitai in a new PR comment to ask questions about the PR branch. For the best results, please provide a very specific query, as very limited context is provided in this mode. Examples:

35-35: 例示パスをプレースホルダで表現すると誤解が減ります
