候鳥遷徙的幾何掛圖

Create one standalone 3:2 landscape image: a geometric wall graphic of migratory birds and wind corridors using triangles, arcs and restrained earth colors, no typography. Visual approach: Edit illustration system. 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：用三角形、弧線與剋制大地色表現候鳥和風廊的幾何掛圖，無文字。視覺方法採用編輯插畫系統。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。
