Refreshing Citrus Coconut Cloud Ice Poster

Goal: Create a refreshing vertical summer beverage poster for {argument name="drink name" default="青柠椰云冰饮"}, with a transparent icy aesthetic, pale cyan palette, and premium minimalist Chinese typography.

Canvas: Tall 9:16 poster, airy high-key lighting, soft sky-blue and white background, faint clouds, sparkling mist, crushed ice, and a glossy water surface reflection at the bottom. Add a soft palm-leaf shadow in the upper right to suggest tropical summer light.

Main subject: Place one large clear plastic cup slightly right of center in the lower-middle of the poster. The cup contains a translucent light-aqua iced drink with visible bubbles, condensation droplets, crushed ice at the top, and exactly 1 round lime slice garnish leaning on the rim. Make the cup rim and walls transparent, glossy, and realistic, with cool highlights and refractions.

Cup label: Add a rounded white label on the cup with teal printing. The label should contain exactly 1 main Chinese drink name, the English subtitle “CITRUS COCONUT CLOUD ICE,” 1 thin divider line, and exactly 3 small line icons: a citrus slice, a coconut with palm tree, and ice cubes. Add small ingredient text at the bottom reading “青柠 | 椰子 | 冰爽”.

Typography and poster text: On the left side, create a very tall vertical headline in thin teal Chinese characters reading {argument name="vertical headline" default="青柠椰云冰饮"}. Near the top-left, add a small vertical slogan reading {argument name="slogan" default="清爽椰云 冰凉入心"} with exactly 1 small lime-slice icon above it and a short hanging dot-line ornament. Near the lower-left, add exactly 3 stacked English words: “Citrus”, “Coconut”, “Cloud Ice”.

Stamp detail: On the right side above the cup, add exactly 1 circular teal seal stamp with a snowflake icon in the center and small Chinese text around the ring suggesting summer recommendation and ice-cool refreshment.

Visual style: Photorealistic product-ad rendering mixed with clean graphic design, elegant thin-line teal typography, ultra-translucent glassy ice, soft bloom, watery reflections, low contrast, generous negative space, fresh coconut-lime summer mood, no people, no clutter, no extra products, no watermark.
