Realistic Tea Poster Metro Station Lightbox Mockup

First generate an original tea poster reference: a vertical premium Chinese tea advertisement with fictional brand name, elegant tea leaves, ceramic teacup, warm paper texture, and fully legible original Chinese typography. Then create a realistic photorealistic metro station lightbox mockup, 8K commercial advertising photography, sharp focus on the vertical illuminated advertising frame. The frame has a matte brushed metal finish, mounted on a clean smooth neutral-toned subway platform wall. Use the generated original tea poster reference as the poster inside the frame, preserving its artwork and Chinese typography without redesign, with no added real brand logos. The poster is perfectly straight, fully legible, and the dominant visual element of the image. The poster is covered by glossy clear glass with subtle soft ambient reflections that do not obscure the poster content. The scene includes light grey non-slip subway floor tiles at the bottom edge, soft diffused mixed warm-cool overhead public transit lighting, and a gentle glow from the illuminated lightbox. A few completely blurred unidentifiable commuters appear in the far background. Shallow depth of field keeps the lightbox and poster perfectly sharp, hyperrealistic texture details, no perspective distortion.
