# Builds a Linux release of the game and attaches it to a Forgejo/Gitea
# Release, so players can download a ready-to-run build and only need to
# bring their own Skate 3 ISO (the built-in installer extracts it).
#
# Runs on the self-hosted runner (see tools/ci/setup_runner.sh and
# docs/ci-releases.md). The runner must have the extracted game dump at
# /opt/skate3-game (default.xex + data/webkit/EAWebkit.xex, and optionally
# the TU_12K2276_* title-update package). The game files are used only for
# codegen; they are NOT bundled into the release artifact.
