# Packaged copies The canonical files live at the repository root (`mews-0.1.css`) and in `dtd/` (`mews-0.1.dtd`), where SPEC.md and `dtd/check_dtd.py` reference them. These copies exist so the validator still finds them when it is installed as a wheel, with nothing but the package on disk. `tests/test_data.py` fails if a copy and its original drift apart.
