Use case: product-mockup. Reference image: warm domestic marble-table scene only. Create a clean vertical 2:3 softly sunlit living-room background with a round pale-gray veined marble table in the lower foreground, an unmarked ivory ceramic teapot and small cup on a simple light-wood tray positioned at lower right, a blurred cream sofa with a warm ochre cushion in the background, a tall window on the left, and a delicate flowering branch entering from the right edge. Leave most of the table surface clear. Cozy neutral editorial photography, shallow depth of field. Change tea-set silhouette, sofa layout, window light, branch form, tray shape, and marble veining so it is related but not identical. No text, numbers, Chinese characters, watermark, logo, brand mark, tiny edge text, border, or white margin.
