    "prompt": "A wide documentary photograph on an empty two-lane gravel road in western Kansas in late June, minutes before a tornado forms. A massive rotating supercell fills the upper two thirds of the sky: a striated, layered mesocyclone shaped like a stacked saucer, dark slate-green underneath, with a low rotating wall cloud on the left side and a thin shaft of hail glowing white behind it. On the right half of the frame, a dusty silver pickup truck is parked on the road shoulder with both front doors open and a tripod-mounted weather instrument mast on its roof. Two storm chasers stand in front of the truck: a tall woman in a faded red windbreaker holds a tablet showing a radar map and points toward the wall cloud; a shorter man in a grey hoodie and baseball cap crouches beside her with a camera on a small tripod. Behind them, golden wheat stubble fields stretch to a flat horizon where a thin strip of warm sunlight breaks under the storm base, lighting the grass and the side of the truck in gold while everything above is dark and heavy. A barbed-wire fence and a leaning wooden utility pole run along the left edge. Strong wind bends the grass and lifts dust from the road. 24mm lens, eye level, sharp foreground, natural color, realistic cloud structure, film grain. No text, no logos, no watermark.",
