+  # Using groups to combine all Go module updates into fewer PRs.
+  # Note: Groups work within each package-ecosystem entry, so we separate:
+  # - Main modules (root, api, properties, tests/e2e)
+  # - Third-party modules (all third_party/* directories)
+  #
+  # Current go.mod files detected:
+  # - / (root)
