The Qt/PySide DLLs and WebEngine resources are shared libraries in _internal.
They may be replaced with compatible modified builds. Keep their dependency
layout and ABI compatible with PySide6/CPython 3.12 x64. Reverse engineering
for debugging modifications of these LGPL components is permitted. DuckoLab
does not require a signature on replacement LGPL libraries.

Other licence/copyright texts in dependencies/ are supplied unchanged from
their installed distributions. They describe their respective components.
