"""
FilterMate Adapters Module.

Implementation of ports for external systems (QGIS, databases, etc.).
Follows hexagonal architecture pattern.

Submodules:
    - backends: Multi-backend filter implementations
    - qgis: QGIS-specific adapters
    - repositories: Data persistence adapters
    - app_bridge: Bridge for legacy FilterMateApp integration
    
For backward compatibility imports, see adapters.compat module.
