Use native built-in image generation ONLY. Create a production 360 degree by 180 degree seamless spherical equirectangular Unity skybox. Exact aspect 2:1. IMPORTANT COMPOSITION: sky occupies only TOP 45 PERCENT of image. Horizon height 45 PERCENT from TOP, not 60 percent. Ground horizon must be ABOVE vertical center, not below. This intentionally compensates a generator that repeatedly put horizon too low. Bottom 55 percent is dim ground with distant low industrial roofs fading into a uniform dark ground nadir, no nearby architecture or obvious aerial city. At quarter-width (NORTH), sprawling space-age CYBERPUNK futuristic skyline with illuminated sleek megatowers rises prominently into upper sky. At three-quarter-width (SOUTH), broad luminous blue RIVER runs horizontally LEFT TO RIGHT, spanning the whole southern quarter, far bank at 45 percent image height and near bank at 52 percent image height, industrial distant river ports on far bank. River is SIDEWAYS east-west, not a canal receding into distance. Half-width WEST low spaceport factories; EAST at both edges low industrial outskirts. No nearby props or roads, all scenery distant and unreachable. Clean coherent detailed architecture, cyan and amber lights, moody blue-hour twilight matching gray concrete site. Left and right edges must connect exactly with continuous matching clouds and terrain: no wrap seam. Smooth featureless dark blue zenith and dark ground nadir, natural latitude compression, no polar pinching. No sun, text, logos, watermarks. Native largest resolution available, ideally 4096x2048.
