### Ellipsis

- Keep ellipsis style consistent with existing Japanese docs (commonly `...`).
- Never change `...` in code, URLs, or CLI examples.

### Preferred translations / glossary

Use the following preferred translations when they apply in documentation prose:

- request (HTTP): リクエスト
- response (HTTP): レスポンス
