Modern Milk Tea Promotional Flyer

Generate a {argument name="Ratio" default="9:16"} vertical restaurant/food brand flyer design. The brand name is "{argument name="Brand" default="蜜雪冰城"}", the food category is "{argument name="Category" default="milk tea / tea drinks"}", and the featured product is "milk tea". The overall visual style should be bright and clean, young and trendy, approachable and good-value, with a strong appetizing feel typical of tea-drink flyers. The color palette should be dominated by a highly recognizable red, pure white, and light cream. Place a large hero product shot of a cup of milk tea in the center area — the cup should look fresh and appetizing. Below it, place a promotions/discount info area that emphasizes the sense of value for money. The layout hierarchy should be clear: brand name > main headline > large product image > promo info > address QR code.
