Mappa HDRI 360 Autostrada Cyberpunk

A 360-degree equirectangular HDRI environment map of a [futuristic urban expressway at night], viewed from the center of a wide, rain-soaked roadway beneath massive elevated highway overpasses. Two large curving highway ramps on the left and right arch inward toward the center, supported by thick pillars and receding overpass layers. The background features a dense skyline of illuminated high-rise skyscrapers with [cool cyan, blue, and purple] window lights. The glossy wet asphalt surface reflects the glowing city lights in horizontal streaks of neon blue, violet, and pink, with subtle luminous light trails across the pavement. The night sky is dark and overcast with atmospheric haze and a subtle glow at the zenith. Full 360 equirectangular panoramic projection with standard polar distortion at the top and bottom edges, realistic high dynamic range lighting, deep indigo and electric cyan color palette, suitable as a 3D environment backdrop.
