Runtime UI Integration Validation
This directory is reserved for interactive XCUI runtime validation apps.
Planned scope:
- HUD and menu layer-stack validation
- Runtime input routing and blocking rules
- Screen stack and modal transitions
For now the runtime UI lane only has automated unit coverage in tests/UI/Runtime/unit/.
