古城门与现代换乘厅相接

Create one standalone 3:2 landscape image: a preserved stone city gate seamlessly integrated with a contemporary timber transit hall, one continuous perspective at blue hour. Visual approach: box within box. Keep a single coherent scene with crisp material edges and believable spatial relationships. No collage, no grid, no logo, no watermark, and no readable text.

生成一张独立的 3:2 横幅图像：古老石城门与现代木构换乘大厅在蓝调时刻自然相接，保持单一连续透视。视觉方法采用框中框。保持单一连贯场景，材质边缘清晰，空间关系可信；不要拼贴、网格、标志、水印或可读文字。
