Create a wide cinematic fantasy sci-fi cityscape at night: an elegant futuristic utopian metropolis made of smooth white organic architecture, sweeping shell-like buildings, ribbed biomorphic towers, arched skybridges, and layered elevated roads curving through the scene. The city should feel vast and luminous, with approximately three dominant foreground megastructures: one large cropped shell-like building on the left, one tall twisting tower-building on the right, and one lower pavilion-like structure in the lower right; include many smaller spires and towers receding into the misty center background. Use {argument name="architectural style" default="white biomorphic solarpunk futurism inspired by shells, bones, and flowing parametric design"}. Add a narrow river or canal winding from the foreground into the center distance, bordered by terraces, bridges, gardens, and softly lit pedestrian paths. Include clusters of pale trees and landscaped parks throughout the city, glowing warm interior windows, delicate dotted facade textures, and tiny human figures for scale. The sky is deep blue-black with a bright full moon near the upper left-center, faint stars, and drifting mist. Color palette: cool moonlit silver, pearl white, icy blue-gray, and warm champagne lights. Lighting should be dreamy and high-detail, with soft volumetric haze, reflective water, crisp architectural surfaces, and an ethereal peaceful atmosphere. Use a panoramic 16:9 composition, ultra-detailed digital concept art, cinematic depth, no text, no logos, no vehicles dominating the scene.
