港灣航海學校動畫場景

Create one standalone 3:2 landscape image: a cel-animation scene of adult sailing students folding canvas in a harbor classroom, wind through open doors, clean color blocks. Visual approach: Constructivism. 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：手繪動畫場景，成年航海學員在港灣教室摺疊帆布，風從敞門進入，色塊乾淨。視覺方法採用構成主義。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。
