潮间带植物蓝晒标本

Create one standalone 3:2 landscape image: a cyanotype composition of tidal grasses, seed heads and fine roots arranged with scientific restraint, deep blue paper. Visual approach: Museum catalog. 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：潮间带草叶、种穗与细根以科学克制方式排列成蓝晒标本，深蓝纸面。视觉方法采用博物馆目录。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。
