Use the supplied reference image as the sole locked product input. Preserve the product's exact appearance, structure, materials, colors, proportions, logo, label, accessories, and product-set relationship.
Create a 561:701 photorealistic commercial product poster. Place the single yellow reed diffuser upright on a yellow pedestal beside a draped yellow-and-white striped towel. Use cream-and-yellow architectural arches, blue sky, hard sunlight, and clean summer shadows.
Use a polished premium advertising finish with crisp product focus, coherent perspective, realistic materials, controlled depth of field, and physically plausible lighting. Keep all decorative elements physically plausible and subordinate to the product. Keep existing product text legible when present. No poster text, watermark, extra product, unrelated logo, distorted object, changed product appearance, or unnecessary person.
