Stylized 3D, vertical 9:16, Pixar cinematic. Two-beat. Beat 1
(mouth-world): the Swit brush (match master_swit_m) blasts the black
spot off the tooth, then docks into the glowing UV case (match
master_uf_m) that zaps the clinging bacteria (match
master_bacteria_plaque_m). Beat 2 (MACRO real): extreme close-up of
the real Swit brush head vibrating on enamel — a black film lifting
to white, foam, droplets; then UV glow sanitizing the bristles.
REVYLINE readable beat 1. No on-screen text.
