Vertical 9:16, one continuous five-second shot. Consistent character identity, clothing, anatomy and object shapes. Restrained believable motion, clean composition, stable lighting, no cuts, no written text, no logos, no captions, no dialogue. Photorealistic selected adult female creative director in a plum blazer, seated beside a closed laptop in a minimalist studio. Hands resting on desk, small confident smile toward camera, medium composition.
