Use case: photorealistic-natural. Create ONE standalone full-bleed premium photographic website background for Snowbound, a coherent collection about the silence and tactile beauty of snow. Scene: 1:1 square. Close landscape photograph of windblown granular snow sculpted into two gently curving shallow ridges, viewed obliquely at snow level. Soft side sunlight on lower right reveals individual frosty powder grains, shadows subtle blue-grey. Upper left half nearly uniform warm-white fine powder, usable for dark small editorial text. Snow should be unmistakeably real and cold, no sand beige, fabric, cream, liquid or paper. Subtle tactile detail, no glitter sparkles. Real editorial landscape photography with plausible cold light, restrained subdued color, natural irregularity and fine film texture, high native detail. Deliberately preserve the stated calm copy space. Avoid artificial gradients, illustration, 3D renders, glossy CGI, surreal shapes, repeated visual motifs, people, footprints, logos, lettering, UI, borders, contact sheets or watermark.
