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 2:3 photorealistic commercial product poster. Place the single green matcha pouch upright on a curved green shelf. Add a glass of iced matcha latte on a lower tray, a mound of matcha powder, loose tea leaves, floating coffee-bean-like accents, and monochrome sage 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.
