    注: プライマリキーのフィールドには `int | None` を使っています。これは Python コード内で `id=None` のように「`id` なしでオブジェクトを作成」し、保存時にデータベースが生成することを想定するためです。SQLModel はデータベースが `id` を提供することを理解し、スキーマでは「NULL 不可の `INTEGER` 列」を定義します。詳細は [SQLModel のプライマリキーに関するドキュメント](https://sqlmodel.tiangolo.com/tutorial/create-db-and-table/#primary-key-id) を参照してください。

* `Field(index=True)` は、この列に対して SQL のインデックスを作成するよう SQLModel に指示します。これにより、この列でフィルタしてデータを読む場合に検索が高速になります。
