 # Concurrency configuration:
-# - We use a named concurrency group to prevent multiple instances of this workflow from running
-#   simultaneously, which could lead to race conditions when creating branches and pull requests.
-#   Since this workflow modifies version files and creates PRs, concurrent runs could interfere
-#   with each other, resulting in conflicting branches or duplicate PRs.
+# - For pull requests, we use a workflow-and-ref–scoped group to keep runs isolated per PR while
+#   still cancelling outdated runs on the same PR.
+# - For non-PR events (schedule, workflow_dispatch, pushes), we use a fixed global group so only
+#   one repository-wide run can execute at a time, preventing race conditions when creating
+#   branches and pull requests.
 # - We enable cancellation of in-progress runs because only the most recent run matters for
-#   version updates. There's no value in completing outdated runs, especially for scheduled
-#   workflows that might queue up overnight. This approach conserves GitHub Actions minutes
-#   and ensures we're always working with the latest repository state.
