撕纸彩虹下的雨水花园

Create one standalone 3:2 landscape image: a municipal rain garden revealed through layered torn paper in spectral colors, wet stones and native grasses, no people. Visual approach: Art Nouveau. 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：层层彩色撕纸缝隙中显现城市雨水花园，湿石与本地草木形成真实空间。视觉方法采用新艺术运动。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。
