         Estimates the size in bytes of a log by calculating the size of its body and its attributes
         and adding a buffer amount to account for other log metadata information.
-        Will process complex log structures up to the specified depth limit.
-        Includes cycle detection to prevent processing the log content more than once.

+        - Returns truncated calculation if depth limit is exceeded
