"prompt": "A lone gunslinger in a black trench coat walks slowly down an empty desert highway, his heavy boots crunching against the pavement. The wind howls softly, dust swirling in the distance. He comes to a stop, raising his pistol with steady precision. A single gunshot echoes through the barren landscape. The camera holds the moment, the smoke drifting from the barrel as the neon lights of a distant roadside bar flicker in the background. Cinematic western-noir, slow deliberate movement, tense atmosphere.",
