+Requires [uv](https://docs.astral.sh/uv/getting-started/installation/).
+Python 3.12 and `.venv` are managed by uv.
+
+```sh
+uv sync --locked
+uv run --locked zensical serve
+```
+
+Build the static site into `site/`:
+
+```sh
+uv run --locked zensical build
+```
+
+Dependencies: `pyproject.toml`; resolved versions: `uv.lock`.
+After editing dependencies, run `uv lock` and commit both files.
