+<!-- END_TF_DOCS -->## Note: resource_group_name normalization
+The module normalizes var.resource_group_name to lowercase internally (local.normalized_resource_group_name) to ensure consistent casing across resources created by the module. Callers may continue to provide resource_group_name in any case; the module will use the lowercase form for resource_group_name references.
