一座船闸的一百年时间线

Create one standalone 3:2 landscape image: one continuous horizontal scene showing a canal lock evolving across four historical engineering stages, aligned masonry and waterline, no labels. Visual approach: paper fiber. 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：横向连续画面展示同一座船闸跨越四个工程时期的变化，石墙和水线对齐，无文字标签。视觉方法采用造纸纤维。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。
