Create one finished standalone photographic website background image, 3:4 portrait, approximately 1536 by 2048 pixels. Theme: Neon afterhours. Scene: A transparent elevated pedestrian bridge crosses a dark futuristic city, sparse cyan edge lights and a distant vermilion light source in haze. Art direction: Cinematic hyperreal cyberpunk environment photography, rich architectural detail and practical lights, controlled atmosphere. Electric cyan and vermilion red separated by black, absolutely no purple or magenta. No legible text, brands, UI, watermarks or cliché flying cars. Composition: retain generous low-detail top space suitable for overlaying website copy, adapting subject placement naturally. This is the actual background artwork, not a website mockup. No text, letters, typography, logos, borders, collages, grids or watermarks. Full-bleed, polished, richly detailed at native resolution.
