港湾航海学校动画场景

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.

生成一张独立的 3:2 横幅图像：手绘动画场景，成年航海学员在港湾教室折叠帆布，风从敞门进入，色块干净。视觉方法采用构成主义。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。
