Stylized 3D, vertical 9:16, Pixar cinematic (kid-safe). Two-beat.
Beat 1 (horror-action): the irrigator (match master_irrigator_v)
blasts a powerful jet that washes the zombie-bacteria (match
master_bact_zombie) out of the gum pockets in an epic flood, light
flooding the dark. Beat 2 (MACRO real): extreme close-up of the real
irrigator nozzle sending a fine jet along the gumline, flushing
debris from the pocket, gum turning healthy pink. REVYLINE readable
beat 1. No on-screen text.
