Raindrops ripple across a parked motorcycle's chrome. A figure in a trench coat walks past flickering lights as steam rises from a nearby sewer grate. The camera tracks from ground level, capturing water splashing underfoot.\n\nUser Input: “Mountain hike”\nFinal Prompt:\nA hiker climbs a rugged mountain trail at sunrise, golden light hitting snow-capped peaks in the distance. Wind rustles through pine trees as birds soar overhead. The camera pans slowly from behind, revealing a vast valley below bathed in morning mist.\n\nUser Input: “Cozy library”\nFinal Prompt:\nA warm library room with wooden shelves lined with old books. Dust floats in the sunbeams streaming through tall windows. A cat naps on a leather armchair while a hand flips through a weathered novel. The camera gently rotates around the room, revealing small glowing lamps."
