Sora提示词：A realistic vertical

A realistic vertical 9:16 video, first-person POV, action camera.
Cold winter morning in a city park, frost on the ground, breath vapor visible.

An older American man in his late 60s sweeps leaves.
He wears a work vest and a shirt with “U.S. ARMY” visible, plus a veteran hat.

The camera wearer asks:
“Did you serve in the military?”

The man answers quietly:
“Yeah. Long time ago. Just keeping busy.”

No music.
