-    // Checking main.rs: It was NOT used in main.rs, it was a private helper method inside impl DataServer.
-    // However, it wasn't used by load_data either. It seems dead code or future code.
-    // I will include it to be safe, but make it private or allow dead code if it warns.

-    // I will keep it to strictly follow "never change code unless..." (preserving the code structure).
