中式茶饮上市海报

Design a 3:4 vertical poster for a new Chinese trendy tea launch. Use a New Chinese visual style that feels light-luxury and restrained. The palette should be dark green, off-white, and gold, with rice-paper texture, elegant negative space, landscape accents, and modern layout design. Main subject: a visually appealing cold-brew tea with tea leaves, citrus, ice cubes, and touches of gold foil. The poster must accurately display the following exact Chinese copy: "山川茶事" / "山柚观音" / "冷泡系列" / "新品上市" "一口清醒，半城入夏" / "限定尝鲜价" "中杯 16 元" / "大杯 19 元" "门店活动" / "第二杯半价" / "加 3 元升级轻乳版" / "每日前 100 名赠限定杯套" "推荐风味" / "观音茶底 / 西柚果香 / 轻乳云顶 / 冰感回甘" "活动时间 4月20日 至 5月10日" / "扫码点单" / "SHANCHUAN TEA" Fine print: "图片仅供参考，请以门店实际售卖为准" Maintain a clear promotional hierarchy while keeping the overall feeling sophisticated rather than cheap or overly e-commerce-like. Pay special attention to small text, numbers, prices, info modules, and Chinese typography aesthetics.
