Create one finished standalone photographic website background image, 16:9 landscape, approximately 2048 by 1152 pixels. Theme: Closer than real. Scene: Macro section of a crystal-clear ice slab with a few trapped air bubbles and tiny natural cracks, raking cold daylight. 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 right 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.
