 - [ ] Extract joystick binding state management into dedicated service modules to trim the QWidget class size.
 - [ ] Normalize data flow between `app/models` and `app/utils` (remove circular imports and duplicated helpers).
 - [ ] Audit `app/models/exported_configmap_xml.py` for dead fields and tighten type hints.
