# The checks of .gitea/workflows/ci.yml, for the copy of this repository on
# GitHub. Gitea reads .gitea/workflows when it exists and then ignores this
# directory, so each forge runs one of the two files, never both.
#
# The jobs, images and commands are the same as there. No action from the
# marketplace is used: the commit is fetched with git from this repository's
# public URL, so nothing outside this file and the pinned images runs. The job
# token can only read.
