- Upload .nitro bundles directly with full DB, catalog, and furnidata integration
- Generate SQL migration files on upload (optional)
- Auto-sync missing furniture from all configured clone sources (SSE batch)
- Repair missing icons by extracting from local .nitro or downloading from sources
- All behind ASSETS_IMPORT permission
