太陽能列車復古旅行海報

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.

生成一張獨立的 3:2 橫幅影象：太陽能列車穿越鹽灘的復古旅行海報，奶油白、紅與青綠的簡化色塊，無文字。視覺方法採用界畫建築。保持單一連貫場景，材質邊緣清晰，空間關係可信；不要拼貼、網格、標誌、水印或可讀文字。
