Use case: product-mockup. Reference image: deep-green interior composition only. Create a clean vertical 2:3 botanical interior backdrop with a rich dark forest-green wall, a warm brass arched wall sconce glowing on the upper left, trailing vines cascading from the upper right, a small pale wood floating shelf with two unmarked green ceramic plant pots on the left, and a sculptural dark-green upholstered chair with light wood legs in the lower right. Keep the middle wall clear as a display area. Soft moody warm lighting, refined editorial decor photography. Change chair contour, plant species, sconce form, vine paths, shelf size, and light pool so it is related but not identical. No text, numbers, Chinese characters, watermark, logo, brand mark, edge text, border, or white margin.
