敦煌矿物色修复工作台

Use case: stylized-concept. Asset type: standalone 3:2 landscape case image. Primary request: an adult mural conservator comparing mineral pigment swatches beside a cave-wall fragment, historically respectful palette, no sacred figure copying. Visual approach: Chalk paper texture, 编辑海报版; keep the medium appropriate to the subject. Composition: one coherent scene, crisp material edges, believable spatial relationships. Constraints: no collage, no grid, no logo, no watermark, no readable text.

生成一张独立的3:2横幅案例图：成年壁画修复师在洞窟墙体残片旁比对矿物颜料样本，色彩尊重历史，不复制具体宗教形象。视觉方法采用粉笔纸纹的编辑海报版，媒介须与主题匹配。保持单一连贯场景、清晰材质边缘与可信空间关系；不要拼贴、网格、标志、水印或可读文字。
