Create one finished standalone photographic website background image, 1:1 square, approximately 1536 by 1536 pixels. Theme: Liquid chrome. Scene: Macro of tightly spaced curved metallic folds resembling tiny dunes, directional white strip reflections, low sculptural horizon. 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.
