A Solarpunk cityscape unfolds as a wide establishing shot pans over the New Harmony Arcology in the former San Francisco Bay, 2157 at golden hour. The eye is drawn upward through a golden ratio spiral composition, leading to a series of interconnected vertical gardens, pedestrian bridges, and cyclists on the foreground, 0-20 meters deep. Behind, terraced buildings blend seamlessly with nature, featuring green walls, wind turbines, and balcony farms, at depths of 20-100 meters. As the camera rises, soaring bio-architecture towers and sky gardens come into view, 100+ meters deep, with birds flying, airships, and sunset clouds filling the background. The atmosphere is serene, with a perfect temperature, gentle breeze, and clear sky, accompanied by the soothing sounds of birds singing, children playing, and gentle music, set against a backdrop of crystal clear air and oxygen-rich plants.
