种子交换会复古海报

Create one standalone 3:2 landscape image: a retro poster of hands exchanging seed envelopes around a circular table, screen-print texture, no readable words. Visual approach: Colored lead color stacking. 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：多双手在圆桌边交换种子袋的复古海报，丝网印刷质感，不出现可读文字。视觉方法采用彩铅叠色。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。
