Every visualizer rendered six times, once per song, each with that song's complete identity — its cast, ink, lattice, palette and sampled parameters. A scene whose six frames are interchangeable is one the song cannot change. Sorted least-varied first, scored on the same structural descriptor the variety harness uses, with colour excluded so six palettes cannot disguise one image. Coverage is shown beside each score because the two explain each other: the highest-scoring scenes are often a few bright elements on black, which is varied and thin to watch on its own. Those are composable — they are meant to sit on top of a canvas. ← all debug tools
