Prompt

Ultra-realistic petite single-tier cake for 4 (short, squat, only 2–3 inches tall). Round. Smooth black fondant with elegant gold marble veining, evenly distributed like polished marble tile (natural, medium veins, not dense, not patchy, no large bare areas). Bottom edge has a thin 1 cm rim of sparkling gold foil flakes (shimmering, textured, light-catching). Modern, classy, no topper. Side + angled top view. Neutral lighting.
