Stylized 3D, vertical 9:16. A child's bedroom at night. The tooth-
mother (match master_r1_mother.png) flings the door open and catches
the toddler tooth-child (match master_r1_child.png) secretly eating
candy under a blanket, candy wrappers scattered, the child frozen
with guilty wide eyes. Dramatic night caught-in-the-act lighting,
glossy enamel, shallow depth of field on the child's guilty face. No
on-screen text.
