Stylized 3D, vertical 9:16, Pixar cinematic. Two-beat. Beat 1
(mouth-world): the black irrigator (match master_irrigator_black)
blasts a powerful water jet that floods and washes the bacteria city
out from under the gumline in an epic splash. Beat 2 (MACRO real):
extreme close-up of the real irrigator nozzle sending a fine water
jet along the gumline, flushing debris from the gum pocket, gum
turning healthy pink. REVYLINE readable beat 1. No on-screen text.
