+# Serialize E2E runs repo-wide. All concurrent runs share the same
+# E2E_RELEASE name (headlamp-e2e) in a single namespace. Without
+# serialization, one run's teardown (if: always()) deletes the
+# deployment while a concurrent run is still using it, causing auth
+# setup timeouts. cancel-in-progress: false queues rather than kills
+# to avoid leaving dangling cluster resources.
