"""
Minimal, standalone crash test - completely independent of the Order
Manager app. Run this directly:

    python minimal_crash_test.py

Click "Open Dialog", then close it (X button or Cancel). If this
crashes the same way (exit code -1073740791 / 0xC0000409), the issue
is in your PyQt6 install/environment itself, not in anything specific
to the Order Manager codebase - every fix attempt there has been
chasing the wrong thing.
