"""pytest: setup.py's data-folder migration (#198) saves the data folder it settled on in the user's settings file
(%APPDATA%\Strata\settings.json, ~/.config/strata/settings.json) and can MOVE model files from a folder it finds there.
A test that reaches it must never touch the real file, so the whole session gets its own config home."""
