怎么填变量：[地铁站灯箱] 可以换成"公交站候车亭广告牌""商场门口的立式海报架""咖啡店墙上的木框画""楼宇电梯里的广告屏"，一张设计稿就能出整套提案样机。

常见问题：

• 海报里的字被"重写"变形：这是改图最常见的问题。把"不要改动主要文字"放在第一句，或者让海报在画面中占得更大。
• 海报被拉伸：上传的海报比例要和灯箱比例接近（竖版海报配竖版灯箱）。
• 乘客太清楚、抢画面：保留"远处、虚化"。

提醒：样机图只用于展示效果；如果画面里出现真实地铁线路标识，商用前请注意相关规定。

Transform the provided tea poster into a realistic metro-station lightbox mockup while preserving the poster artwork and Chinese typography as much as possible. Show the poster behind glossy glass in a vertical illuminated advertising frame on a clean subway platform wall. Add subtle reflections, brushed metal frame, floor tiles, soft overhead transit lighting, and a few blurred commuters in the distance. Keep the poster straight, legible, and dominant; do not redesign the poster, do not change its main text, and do not add fake brand logos.
