Create one finished standalone photographic website background image, 21:9 ultrawide, approximately 2520 by 1080 pixels. Theme: Earth from above. Scene: Panoramic high-altitude view of a thin foamy white coastline dividing muted sand below from expansive clear blue sea above. Art direction: Hyperreal high-altitude landscape photography, natural geologic detail and credible colors. Strong abstract composition, no people or buildings, no artificial purple, no text. Photographic natural light, no painterly styling. 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.
