极简主义日式咖啡馆产品海报

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.

创建一张极简主义的 4:5 咖啡馆产品海报，采用纯白背景和黑色排版。使用附带的产品照片作为主要参考，或者在未提供照片的情况下根据产品名称生成逼真的产品图像。以大写英文文本显示产品名称，价格完全按照输入的内容显示，并仅生成简短的英文宣传短语。保持一个产品居中并带有柔和的自然阴影，采用干净的瑞士风格编辑布局，宽边距，以及现代日系咖啡馆审美。不要虚构不可见或未暗示的成分、品牌或特征。
