印花覆盖区与未印玻璃层次

提示词

让选定印花在同一片连续玻璃上形成覆盖区，未印区域保留可透视背景，表面反射跨越两者但按实际材料与视角变化，图案空隙不画成穿孔。 若减小或移动印花会显露原图未知的后景，须先提供对应后景参考；缺资料的区域保留原状并标待核，不用生成补造。

Place the selected print as covered areas on one continuous glass pane, retain background visibility through unprinted areas, and let surface reflections continue across both with the actual material and viewpoint; do not turn pattern gaps into holes. If reducing or moving the print would reveal background unknown in the base image, first provide a corresponding background reference; retain and flag unsupported areas rather than inventing them through generation.
