"""
Database models for Letzshop marketplace integration.

Provides models for:
- VendorLetzshopCredentials: Per-vendor API key storage (encrypted)
- LetzshopFulfillmentQueue: Outbound operation queue with retry
- LetzshopSyncLog: Audit trail for sync operations
- LetzshopHistoricalImportJob: Progress tracking for historical imports

Note: Orders are now stored in the unified `orders` table with channel='letzshop'.
The LetzshopOrder model has been removed in favor of the unified Order model.
