+        help
+            Limits how deeply nested arrays/objects can be before cJSON
+            rejects to parse them. This is to prevent stack overflows.
+            Lower values use less stack, higher values allow deeper nesting.

+        int "Maximum depth for circular reference detection"

+        help
+            Limits the depth for circular reference detection during
+            printing/comparison operations. This prevents infinite loops
+            and stack overflows when processing JSON structures with
+            circular references. Lower values use less stack.
