EVALUATION
Blank noise-textured canvas with no visible fluid simulation and no response to any input.

MEASUREMENTS
Raw readings from the capture, not a verdict — the grade above is the only judgement. Percentages are how much of the screen changed; the measure under-reports sparse motion on a dark background.
