Ultra-realistic top-down photograph of detergent foam forming a precise [subject / logo / symbol / shape] on a polished black marble surface. Thick, airy white foam with realistic bubbles of varying sizes, natural translucency, wet shine, and soft highlights. Foam appears freshly formed, slightly uneven at the edges, physically accurate, volumetric, and naturally settled on the marble.
