+# # Max deserialization determines the maximum payload size for record payloads (key/value/headers)
+# # that are sent to the frontend when listing messages. Payloads that exceed this value will be
+# # omitted. If you try to inspect very large messages on the frontend, this will crash the frontend
+# # application due to resource constraints in the browser. To avoid these crashes, you can limit
+# # the size here. Records can still be downloaded using the "Save to file" action regardless of this size.
