# The Steamify ISO's release, step 2 of 2 (the Gitea mirror, git.upriser.nl, on its own runner): builds the
# ISO for a release tag that iso-1-github-tag.yml created on GitHub (it comes in with the mirror's sync, and a
# release on the mirror only survives its syncs when its tag comes from GitHub), then attaches the ISO, its
# checksums and package list to the mirror's release for that tag. The tag names the Steamify version and
# the time: v<steamify>-<YYYY.MM.DD>-<HHMM> (master) or v<steamify>-dev.<...> (feat/steamify, a pre-release);
# the ISO gets exactly that Steamify release, and its label the same moment. GitHub skips it.
# Two jobs: build the ISO -> release it. The VM tests run on GitHub (steamify-cachyos vmtest.yml, the newest ISO release of
# this mirror), where the runners are bigger.
# The runner needs privileged containers (archiso mounts loop devices) and ~20 GB of disk; Gitea's
# [repository.release] FILE_MAX_SIZE must allow the ISO (default 2 GB).
