Development

This project uses pre-commit with Ruff for linting and formatting.

To set up pre-commit hooks:

python -m pip install pre-commit
pre-commit install

Run on all files once:

pre-commit run -a

Ruff lint will auto-fix simple issues on commit; if it makes changes, the commit will fail so you can review and re-commit.
