 - Prefer app-level enums (string columns + validation) over DB `ENUM`.
 - Use `cascadeOnDelete()` only where child data must be removed with parent; otherwise `nullOnDelete()`.
 - Every tenant-owned table should include `tenant_id` and appropriate composite indexes.
+- **i18n Integration**: JSON fields (e.g., `name`, `description`) store locale-specific values as `{ "de": "Text", "en": "Text" }`. Use Laravel's `json` cast or spatie/laravel-translatable for access. Fallback to `default_locale` or global fallback ('de'). Update via Filament resources with locale selectors. Ensure indexes on JSON paths if querying (e.g., `->de` for German titles).
