Pixar 3D animation style, vertical 9:16. Modern dental office. Viktor (match master_viktor.png EXACTLY —
skeptical man ~45, plaid shirt) sits in the dental chair, arms crossed, waving a dismissive finger "no" at
the toothbrush, frowning stubbornly. Dr. Homa (match master_homa.png EXACTLY — ginger hamster dentist)
stands calmly beside, holding the white DOHEALTH ELECTRIC SONIC toothbrush (match master_brush_white.png
EXACTLY — thick powered handle, round power button + M button, sharp printed "Clean/White/Polish/Milder/Soft"
and "DOHEALTH" labels, oval brush head).
(Viktor = human skeptic refusing; Homa = patient dentist with the electric tool.)
NEGATIVE: brush is an ELECTRIC powered handle, NOT a thin manual brush; labels sharp like real product;
human realistic-stylized not uncanny; brush no face; no text overlays / subtitles / captions on screen.
