Create a minimalist 4:5 café product poster with a pure white background and black typography. Use the attached product photo as the main reference, or generate a realistic product image from the product name if no photo is provided. Display the product name in large uppercase English text, the price exactly as entered, and generate short English promotional phrases only. Keep one centered product with soft natural shadows, a clean Swiss-style editorial layout, wide margins, and a modern Japanese café aesthetic. Do not invent ingredients, brands, or features that are not visible or implied.
