+# Google Play allows only one active "edit" per app, so two release builds
+# publishing at once make the second fail with "This edit has expired, please
+# create a new Edit." Serialize the release-publishing runs (pushes to dev/main
+# and v* tags) into a single queue so they never overlap on the Play API.
+# cancel-in-progress is false so an in-flight publish finishes rather than being
+# killed mid-upload. Pull request runs get a unique group keyed to run id, so
+# they never queue and CI stays fast.
