透明水迴圈課堂教具

Create one standalone 3:2 landscape image: a tactile classroom model of watershed, reservoir, treatment plant and river made from transparent colored resin, physically connected. Visual approach: ceramic matte. 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：用透明彩色樹脂製作的流域、水庫、處理廠與河流課堂教具，各部分水路真實相連。視覺方法採用陶瓷啞光。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。
