"""Common fixtures for the KACO Modbus tests.
The mock is loaded with a register image captured from a real blueplanet
8.6 TL3 INT, so everything below the connection is the library's own code
reading a real SunSpec map rather than a stubbed device. A test that needs a
different device overrides ``register_image``.
