Create a polished vertical 2:3 commercial product display background with an empty product placement area or central display platform, clean full-bleed composition, refined studio lighting, high-quality 3D render or photorealistic product-photography finish, decorative elements that are related to the scene theme but not copied exactly, adjusted colors, positions, angles, proportions, and small details, no readable text, no numbers, no Chinese characters, no watermark, no brand logo, no trademark symbols, no tiny edge text, no dirty edge, no disconnected blank margins, and no border.
