The freeze target is docgen-gui: a Vue window over the local Flask wizard (benchmark view first). It is not a frozen copy of the full docgen CLI (Manim / ffmpeg / OpenAI stay on the pip tool).

pip install -e '.[packaging]'
pyinstaller packaging/docgen-gui.spec
# dist/docgen-gui/docgen-gui

From a source checkout you can run the same entry without freezing:

pip install -e '.[gui]'
docgen gui                 # pywebview window if the extra is installed
docgen gui --browser       # system browser fallback
docgen gui --config path/to/docgen.yaml
docgen benchmark --gui
python -m docgen.gui

Asset paths use docgen.resources.package_root() so templates, static Vue files, and benchmark_data/ resolve both in an editable install and under sys._MEIPASS after PyInstaller.
