Utility Operations
resource: utility — local helpers, no network call
No network call: Both operations on this page run entirely locally — they don't hit
the Mirror Node, so they work regardless of network configuration and have no eventual-consistency
delay.

utility.validateAddress on user-entered account IDs before
passing them to account.getBalance or any other network call — it's a free, instant
guard against malformed input reaching the Mirror Node.
