主体密线与环境疏线

提示词

保留给定主体内部的细密线描，主轮廓适度加深，环境用较淡且稀疏的线衬托；信息密度随对象层级变化，不靠新增零件、暗线团或抹去已知轮廓制造主次。

Retain the supplied subject’s fine, dense internal linework, strengthen its main outline slightly, and use paler, sparser lines for the context. Vary information density by object hierarchy without adding parts, dark tangles or erasing known contours to manufacture emphasis.
