"""Tests for ChattoClient.

Since the client now goes through generated ConnectRPC service stubs, tests
mock at the service-client method level with ``AsyncMock`` rather than at the
HTTP transport layer. This exercises the request-building and response-parsing
paths without any real network traffic.
