Use case: product-mockup. Reference image: calm modern living-room symmetry and neutral palette only. Create a clean vertical 2:3 Scandinavian living room with a large shallow arched wall niche centered behind a warm ivory two-seat sofa, two tall leafy potted plants at the far left and far right, light cream wall paneling, pale wood floor, a low round light-oak coffee table in front of the sofa, and a soft off-white rug. Soft natural window lighting, uncluttered editorial home photography. Change sofa silhouette, pot forms, leaf shapes, arch proportions, rug texture, and coffee-table profile so it is related but not identical. No text, numbers, Chinese characters, watermark, logos, brand markings, tiny edge text, border, or white margin.
