橋樑節點藍曬圖

Create one standalone 3:2 landscape image: cyanotype study of riveted bridge joints, gusset plates and cable anchors, precise overlapping silhouettes, no text. Visual approach: Art Nouveau. 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：鉚接橋樑節點、連線板和索錨的藍曬研究，輪廓疊加準確，無文字。視覺方法採用新藝術運動。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。
