撕紙彩虹下的雨水花園

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.

生成一張獨立的 3:2 橫幅影象：層層彩色撕紙縫隙中顯現城市雨水花園，溼石與本地草木形成真實空間。視覺方法採用新藝術運動。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。
