 # Tag pushes are intentionally NOT a trigger — release.yaml handles tags and
 # also produces the disk image. Triggering both on the same tag wastes an
 # hour of Odroid time on a duplicate kernel build.
+#
+# `paths-ignore` keeps workflow-file and docs-only commits from kicking off
+# a 60-minute Odroid rebuild. If you change a kernel fragment, init script,
+# or build/script, this WILL fire — that's by design.
