Comment:
`aria-invalid` が未設定のため、スラッグが「使用済み」または「無効」な状態でも入力フィールドがエラー状態であることをスクリーンリーダーに伝えられていません。`aria-describedby` でステータスメッセージは読み上げられますが、`aria-invalid="true"` がないと一部のスクリーンリーダーはフィールドがエラー状態であることを明示的にアナウンスしません(WCAG 1.3.1 / 4.1.2)。
```suggestion
aria-describedby="slug-status"
aria-invalid={slugStatus === "taken" || slugStatus === "invalid"}
className="w-full rounded-md border border-gray-300 px-3 py-2 text-sm dark:border-gray-700 dark:bg-gray-900"
```
How can I resolve this? If you propose a fix, please make it concise. |

スラッグのバリデーション状態(
invalidまたはtaken)に応じて、入力フィールドにaria-invalid属性を動的に付与することをおすすめします。これにより、スクリーンリーダーなどの支援技術が、入力フィールドが現在エラー状態であることをユーザーに即座に伝えることができるようになり、アクセシビリティがさらに向上します。
