+# NOTE:
+# This workflow may be triggered twice in quick succession when a PR is
+# created:
+#   1) `opened`  — when the pull request is initially created
+#   2) `labeled` — if labels are added immediately after creation
+# (e.g. by manual labeling, another workflow, or GitHub App).
+#
+# These are separate GitHub events, so two workflow runs can be started.
+# The `concurrency` configuration below ensures that only the latest run
+# for the same PR remains active, canceling any previous in-progress
