Create one finished standalone photographic website background image, 21:9 ultrawide, approximately 2520 by 1080 pixels. Theme: Liquid chrome. Scene: An ultrawide low horizon of rippling chrome liquid illuminated by a long white softbox reflection, the upper two thirds absolute black. 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 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.
