"""Quickstart: score model outputs with the Canary engine straight from the Hub.
pip install huggingface_hub pandas

Nothing here calls a model: you bring outputs you already generated.
Run it as a file (not through stdin): the engine runs user regexes in a worker process
that re-imports the main script on macOS and Windows.
