+# maintainer's own Minecraft files (Horizon never downloads the game). Called by ci.yml for pull requests from this repository
+# and by run-parity.yml when a maintainer labels a fork's pull request run-parity. See docs/release-flow.md.

+          runs on playhorizon's runner only, so the Mac mini's runners stay free for the others. While that runner is
+          busy the job waits for it.
