# Entry conditions:
# - `setup/checkout` has already happened
# - working dir is the root directory of your project (e.g. `reflex/`).
# - You have a `uv.lock` file in the root directory of your project
# - You have a `pyproject.toml` file in the root directory of your project
#
# Exit conditions:
# - Python of version `python-version` is ready to be invoked as `python`.
# - Uv of version `uv-version` is ready to be invoked as `uv`.
# - If `run-uv-sync` is true, deps as defined in `pyproject.toml` will have been installed into the venv at `create-venv-at-path`.
