Create one finished standalone photographic website background image, 1:1 square, approximately 1536 by 1536 pixels. Theme: Closer than real. Scene: Extreme macro of a fractured graphite slab with thousands of fine metallic layers catching a narrow white light on the right. Art direction: Hyperreal macro photography, physically believable textures, shallow optical depth of field used sparingly, exceptionally sharp primary detail, luxurious restrained editorial lighting. No CGI plastic appearance 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.
