Vertical 9:16. One continuous five-second photorealistic shot. Natural stable anatomy, consistent identity, clothing and object shapes throughout. Gentle believable motion only. Clean premium composition, no cuts, no text, no logos, no captions, no dialogue. The selected adult character age 35 wears a charcoal business jacket over a white shirt in a modern warm office. Waist-up shot, look at the camera, nod once naturally, friendly composed expression. Hands resting on a desk, stationary laptop at the side, soft daylight.
