"""Unit tests for the --cpu-offload device-placement branch.

``WatermarkRemover._move_to_device_and_optimize`` chooses between a full
``pipeline.to("cuda")`` and ``enable_model_cpu_offload()``. The placement
decision is exercised with a mock pipeline and an uninitialized remover, so the
core CI matrix needs no diffusion dependency, model download, or GPU.
