按样板保持直纹类型

提示词

依据已选直纹样板，在指定木饰面预览中保留沿给定方向延伸的近直线纹理，不添山形拱纹；板块边界和排板顺序保持，纹理疏密与板间变化按确认样板范围，不用同一花纹连续盖章。

In the selected wood-finish preview, follow the approved straight-grain sample with nearly linear grain along the specified direction, without adding cathedral-shaped arches. Retain panel boundaries and their layout sequence, following the sample’s grain density and permitted panel variation rather than repeatedly stamping one identical pattern.
