# Important: Do not be tempted to cache the .venv dir (Python virtual environment).
# When the runner environment changes (e.g. Python is upgraded), the venv will need to be
# re-created. Trying to upgrade a venv can be complex and it's usually more practical re-create it.
# We don't save much time anyway by caching the venv so it's not worth the added complexity.
