+// MapleDeploy branding: threshold-based Docker cleanup by default.
+//
+// Upstream defaults to a forced cleanup once a day (00:00). On a managed
+// instance whose only server is the VM itself, a build-heavy app can fill the
+// disk between two daily runs (titanreach, 2026-08-29: ~30 deploys of a 2.5 GB
+// image in one evening, ENOSPC mid-build, deployment queue stuck). The
+// scheduler dispatches on docker_cleanup_frequency regardless of the force
+// flag; with force off, the job only prunes when usage exceeds the threshold.
+// Checking every 10 minutes and pruning above 75% catches fast fills without
+// pruning on servers that do not need it.
