Minimalist Japanese Cafe Product Poster

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 {argument name="product name" default="product name"} if no photo is provided. Display the product name in large uppercase English text, the {argument name="price" default="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 {argument name="aesthetic" default="modern Japanese café"} aesthetic. Do not invent ingredients, brands, or features that are not visible or implied.
