茶饮海报地铁灯箱

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.
