砂铸铝椅留着颗粒表面

One standalone original industrial design photograph, landscape 3:2: a functional low chair made from sand-cast aluminum in a quiet design workshop. The seat, back and four stable legs form a plausible continuous structure; rough granular casting texture and polished contact edges are visible, with a sand mold softly out of focus behind. Three-quarter camera view, soft side daylight, no people, text, branding, watermark, collage or impossible joints.

横幅工业设计照片：安静工作室中的一把低矮砂铸铝椅，座面、靠背和四条稳固椅腿连接合理。三分之四视角可见颗粒铸造肌理与边缘抛光，远处砂模柔焦，侧窗光勾出承重构造，不出现人或品牌。
