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 3:4 photorealistic commercial product poster. Show one hand lifting the single lavender power bank from the open zipper of a tan leather bag. Include a purple phone and tortoiseshell hair clip in the lower foreground, a blue sky opening, and warm travel-editorial light.
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.
