+# Explanation of the concurrency group:
+# The 'group' value is dynamically determined based on the context of the workflow trigger.
+# - If the workflow is triggered by a push to the 'main' branch (github.ref == 'refs/heads/main'),
+#   it uses the group name 'auto-deploy'. This groups all main branch workflows together, allowing
+#   newer runs to cancel in-progress runs, ensuring only the latest push to main is deployed.
+# - For pull requests, the group name is set to a unique value for each run using the format
+#   'pr-{run_id}'. This ensures that workflows triggered by pull requests each have their own 
+#   concurrency group, so they don't cancel each other and are not affected by main branch workflows.
