Create one finished standalone photographic website background image, 3:4 portrait, approximately 1536 by 2048 pixels. Theme: Black light. Scene: One tiny brilliant white specular glint on an almost invisible black metal curve near the lower right, barely visible scattered dust. 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 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.
