"prompt": "Photorealistic automotive campaign photograph of one unbranded scarlet-red two-door sports coupe accelerating along an empty closed desert test circuit at golden hour. Low front three-quarter tracking-camera view, car pointed to the right, entire car and all visible wheels inside the frame. Sculpted low bonnet, simple narrow headlights, black five-spoke wheels, dark windows, realistic red paint reflecting the warm sky. The car body is crisp while the spinning wheels and asphalt show controlled directional motion blur. Pale desert hills, a sweeping bend and trackside barriers recede behind it. Dynamic but physically believable, natural light, realistic scale and geometry. Leave generous space ahead of the car and keep its complete silhouette within the middle 60 percent of the image height for a later widescreen crop. No other vehicles, no people visible, no badges, no brand logos, no words, no watermark. Landscape photograph, not an illustration.",
