IG 方形信息流广告——倒计时上新预告

生成一张 4:5 竖版 1024x1280 的社交媒体信息流美妆新品倒计时海报，虚构奢华美妆品牌使用「示例产品」。极简高时尚版式，近黑色背景。上三分之二居中放置单一产品预告物：竖向长方形磨砂深灰玻璃，完全不透明，像独石碑般直立，顶部聚光灯沿中心形成一条镜面高光线，暗示隐藏香氛瓶轮廓但不露出品牌瓶身。物体在镜面抛光底面投出清晰修长阴影。下三分之一用白色超细中文无衬线文字三行居中排版：小号「07」，巨大数字「07」，下方「天后揭晓」。无行动按钮，神秘高级感，所有可见文字必须为中文，不出现真实平台名称、真实应用图标、水印或外部标志。

A 1080x1080 px Instagram feed square ad serving as a product-launch countdown teaser for a fictional luxury beauty brand called Nocturne Paris. Stark, high-fashion minimalist layout on a near-black background. Centered in the upper two-thirds: a single product teaser — a perfect vertical rectangle of frosted deep-grey glass, completely opaque, standing upright like a monolith with a single specular highlight line from a top spot running down its center — suggesting but not revealing a perfume bottle silhouette beneath. The frosted-glass object casts a crisp elongated shadow beneath it on a mirror-polished surface. No product name visible on the object. Typography in the lower third, in pure white ultra-light-weight sans-serif: three lines — "Nocturne Paris" at small elegant size, then a much larger "07" (the countdown number) centered, then below it "Days Until It Arrives" in matching small light weight. No CTA — the mystique IS the call to action.
