Sora提示词：A realistic vertical

A realistic vertical 9:16 video, first-person POV, action camera.
Cold winter morning, visible breath vapor.

An older American man in his late 60s stands behind a small outdoor market stall.
He wears gloves, a jacket, and a shirt with “ARMY” text visible, plus a veteran cap.

The camera wearer asks:
“Did you ever serve?”

The man answers simply:
“Yeah. A long time ago.”

No music. Realistic ambient sound.
