Colossal floating industrial city buried in turbulent clouds

An epic cinematic sci-fi scene deep inside the upper atmosphere of Jupiter, showing a colossal futuristic industrial city floating entirely among enormous clouds. The planet itself is NOT visible — no planetary surface, no horizon, no view of Jupiter from space, only endless layers of turbulent clouds surrounding and partially obscuring the city. The immense city is built on a gigantic reinforced steel platform suspended in the atmosphere by hundreds of enormous futuristic helium balloons, massive buoyancy chambers and industrial lifting structures. The architecture is dark, heavy and industrial: gigantic steel towers, interconnected metal platforms, enormous pipes, ventilation systems, cables, cranes, machinery, docking platforms, industrial complexes and massive structural beams. The city feels like a gigantic airborne industrial megastructure rather than a clean futuristic metropolis. Huge transparent reinforced glass domes cover sections of the city, protecting industrial districts, residential areas and infrastructure from the extreme atmosphere. The domes are supported by thick steel frameworks and connected by enormous metallic bridges and tunnels. Countless small lights glow through the fog, creating a sense of a vast functioning civilization. The floating city is surrounded on every side by spectacular layers of Jupiter's clouds — enormous swirling formations in deep orange, rusty red, ochre, golden yellow, cream, dark brown, muted blue and pale turquoise. Thick clouds pass both in front of and behind the city, creating tremendous atmospheric depth and making the city appear to float inside an endless alien ocean of clouds. Powerful sunlight breaks through the clouds from above, creating dramatic volumetric rays, illuminating parts of the steel structures while other sections disappear into dark atmospheric shadows. Strong contrast between warm sunlight, dark metallic architecture and colorful alien clouds. Moisture, mist, atmospheric particles and clouds partially covering the structures. Extreme sense of scale: the city is gigantic, with enormous industrial structures and platforms disappearing into the clouds, yet the surrounding atmospheric formations are vastly larger. No visible stars, no outer space, no planetary surface, no curvature of Jupiter — completely immersed inside the atmosphere. Dark industrial sci-fi aesthet
