# Continuous integration for the squirrel census project: lints the YAML and
# workflow files and runs the pytest tests on Python 3.13 for every push and
# pull request. Read by Gitea Actions (a runner must be registered for the
# repository). It changes nothing outside the repository and uses no secret.
# Decision: MIL-001 task "Add CI workflow".
# Host: Gitea Actions; uses only github.* contexts, so it also runs on GitHub.
