種子交換會復古海報

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.

生成一張獨立的 3:2 橫幅影象：多雙手在圓桌邊交換種子袋的復古海報，絲網印刷質感，不出現可讀文字。視覺方法採用彩鉛疊色。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。
