Use case: product-mockup. Reference image: muted sage circular niche, central cylinder, and dark botanical leaves only. Create a clean vertical 2:3 product display scene in soft sage green with a large shallow circular wall niche centered behind a wide low off-white speckled cylindrical podium in the bottom foreground. Frame the scene with deep-green tropical leaves entering from the lower left and lower right, with long quiet leaf shadows. Keep the podium empty. Premium studio 3D render with diffuse natural light. Change niche proportion, leaf species, podium texture, wall panel details, and shadow direction so it is related but not identical. No text, numbers, Chinese characters, watermark, logo, brand, tiny edge text, border, or blank margin.
