"""PyInstaller spec for the Behavision engine.

One-folder, not one-file. A onefile build of this is ~200 MB and extracts the
whole thing to a temp directory on **every** start, which on a store PC means a
multi-second delay and an antivirus scan each time the service restarts.

Models are NOT bundled. They are ~200 MB on their own and `setup-models`
already downloads them with a resumable `.part`-then-rename; bundling them
would triple the installer and force a re-sign for a model change. They land in
the writable state root (see behavision/paths.py), not next to the code.

Build:
    pyinstaller behavision.spec --noconfirm
Output:
    dist/behavision/behavision.exe
