Create one finished standalone photographic website background image, 16:9 landscape, approximately 2048 by 1152 pixels. Theme: Neon afterhours. Scene: An empty underground corridor lined with dark server-like metallic panels and narrow red status lights, cyan ambient spill, reflective wet stone. 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 right 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.
