太阳能列车复古旅行海报

Create one standalone 3:2 landscape image: a retro travel poster of a solar train crossing salt flats, bold simplified shapes, cream red and turquoise, no text. Visual approach: boundary painting architecture. 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：太阳能列车穿越盐滩的复古旅行海报，奶油白、红与青绿的简化色块，无文字。视觉方法采用界画建筑。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。
