EVALUATION
Tetris menu screen renders with UI and preview, but game never starts—no input triggers gameplay across any test.

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.
