Module print_gpu 

cargo xtask print-gpu: describe the device the tests draw with.

A snapshot mismatch is usually a disagreement between drivers, so a CI log that names the backend, adapter, features and limits is what turns a score into something a reader can act on. The task runner links no graphics code, so the description comes from unlit_wgpu_test_util’s gpu-info binary, which is built and run here.

A test run draws through two tiers – the default one, then webgl2 – so both are described, each labelled with the tier it belongs to.
