Chinese Co-Branded Summer Drink Poster

Create a glossy Chinese co-branded beverage poster advertisement in a bold commercial style, vertical 4:5 composition, with a dramatic split-color background: bright saturated red on the left and vivid royal blue on the right, blended at the center with radiant streaks, motion lines, glow effects, and high-energy product-launch lighting. At the top, place 2 brand logo areas separated by a white multiplication sign: on the upper left, a snowman mascot logo with Chinese text [left brand name] and smaller subtitle text "始于1997冰淇淋与茶"; on the upper right, the deer logo and wordmark [right brand name] with smaller Chinese subtitle "专业咖啡新鲜式". Centered beneath the logos, add a huge Chinese headline in thick 3D extruded display typography with white faces, colored edging, heavy shadows, and a glossy embossed look, reading [headline text], with the left half accented red and the right half accented blue. Below it, add a second slogan line in bold Chinese text, split by brand color, reading "冰爽甜蜜，咖啡加倍", flanked by short horizontal white dashes. Under that, place a rounded capsule banner in red-to-blue gradient containing the Chinese text "双品牌联名主打・人气招牌同框". In the center foreground, show 2 hero products: on the left, 1 vanilla soft-serve ice cream in a waffle cone, tall swirl, creamy white, slightly glossy, wrapped in a bright red cone sleeve printed with the snowman mascot and Chinese branding; on the right, 1 large clear plastic cup of iced latte or coffee with visible ice cubes, caramel-brown liquid marbling into milk, condensation droplets on the cup, a transparent lid, the blue deer logo, the wordmark "luckin coffee", and small Chinese subtitle text. Surround the cup with dynamic coffee splash arcs and exactly 3 flying coffee beans. Around the lower foreground, add scattered translucent ice cubes and white milk splashes to emphasize cold freshness. Include exactly 2 comic-style promotional burst badges: a red circular badge on the left reading "联名新品" and a blue circular badge on the right reading "限时热卖". In the bottom left corner, add 1 cute 3D snowman mascot character wearing a red cape and holding a tiny ice cream cone, smiling and winking. At the bottom center, place a large red-and-blue beveled ribbon banner with bold white Chinese text reading "今夏限定 立即尝鲜", ending with a yellow lightning bolt icon on the right. Along the very bottom edge, place 3 small selling-point items separated by vertical dividers: a snowflake icon with "冰爽甜蜜", a coffee bean icon with "咖啡加倍", and a heart icon with "双倍满足". Use premium e-commerce poster rendering, ultra-clean product retouching, glossy highlights, rich contrast, crisp Chinese typography, depth, reflections, splash effects, and an energetic summer limited-edition campaign aesthetic.
