Stylized 3D, vertical 9:16, Pixar style. Two-beat. Beat 1 (mouth-
world): the capybara brush (match master_capybara) sweeps over the
tooth, soft sonic waves blasting the plaque army (match
master_bacteria_plaque) off in a foamy splash. Beat 2 (MACRO real):
extreme close-up of the real capybara brush head on enamel — soft
bristles vibrating, white foam, droplets, plaque lifting to clean
glossy enamel. REVYLINE readable beat 1. No on-screen text.
