Create one finished standalone photographic website background image, 16:9 landscape, approximately 2048 by 1152 pixels. Theme: Liquid chrome. Scene: One thin polished steel ribbon twists in a precise angular loop at the right, mirror reflections sharply controlled, matte black background. Art direction: High-end photoreal material study of polished liquid metal, physically plausible studio reflections, crisp silver, graphite and restrained ivory. Sculptural deliberate forms rather than soft generic blobs. No purple, no text. Composition: retain generous low-detail left 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.
