## Summary by CodeRabbit

- **Improvements**
- Recovery codes now appear in a dedicated section when enabled,
separate from multi-factor authentication settings.
- Recovery-code status updates are announced to screen readers for
improved accessibility.
- Available recovery codes are displayed in a clearer card-based layout
once status information is available.
