Use only the native built-in image generation tool, not code drawing or external APIs. Generate a seamless full spherical 360 by 180 degree equirectangular skybox panorama, exact 2:1 ratio, preferably 4096x2048. Space-age cyberpunk industrial neighborhood at blue-hour with restrained cyan and amber lights and realistic clean architecture. Everything is distant horizon scenery: no nearby objects, no railings, no foreground vehicles. Full upper half sky with smooth clouds, level horizon at image midline. Direction layout along image width: LEFT edge and RIGHT edge are EAST and must seamlessly connect; 25 percent width is NORTH with sprawling dense magnificent sci-fi city skyline and high skyscrapers; CENTER is WEST with low industrial neighborhood; 75 percent width is SOUTH with a broad distant river flowing east-west, viewed SIDEWAYS across its width, water spanning horizontally across the southern quadrant, long straight parallel banks running left-right not toward camera, sparse low industrial far bank. City skyline only in northern quadrant, river only in southern quadrant. Full spherical projection including naturally converging featureless nadir and zenith; no text, labels, compass, border, collage, duplicated landmarks, sun disk, grain, or ornamental noise. This is distant backdrop for existing Unity gray-box construction playground, not navigable geometry.
