火山地貌豎版觀察海報

Create one standalone 3:2 landscape image: a tall editorial poster with one volcanic cone, lava textures, ash layers and a tiny observer for scale, no text. Visual approach: one point perspective. 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：豎版編輯海報，以單一火山錐、熔岩紋理和灰層為主體，小觀察者提供尺度，無文字。視覺方法採用單點透視。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。
