Create one finished standalone photographic website background image, 16:9 landscape, approximately 2048 by 1152 pixels. Theme: Black light. Scene: A hair-thin warm amber seam of light along the right edge of two nearly invisible black stone planes, three or four tiny airborne glints. Art direction: Minimal high-end studio light photography. At least 80 percent of the frame is true near-black. Only tiny sparse dust motes, subtle realistic bloom, no oversized bokeh, no dense glitter, no stars drawn as icons, no purple or text. 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.
