+> This project uses [uv](https://docs.astral.sh/uv/) with two constraints worth knowing:
+>
+> - **uv version**: a specific version range is required (see `pyproject.toml`). If uv refuses to run, update it with `uv self update`.
+> - **Dependency cooldown**: packages published to PyPI less than 7 days ago are ignored during resolution, as a supply chain security measure.
