# The Steamify ISO, built and released on the Gitea mirror (git.upriser.nl) by its own runner: the same
# build as by hand (the wsl-build-host skill in steamify-cachyos-dev), then a Gitea release v<date> with the ISO,
# its checksums and package list, notes from CHANGELOG.md's Steamify section. GitHub skips it (one file
# for both servers; GitHub releases take at most 2 GB per file, the ISO is bigger).
# The runner needs privileged containers (archiso mounts loop devices) and ~20 GB of disk; Gitea's
# [attachment] MAX_SIZE must allow the ISO (default 2 GB).
