A triply-periodic minimal surface (Schwarz-D morphing gyroid) suspended in void, breathing in porosity and rotating through oblique planes. 骨质微孔随相变开合，虚空留白界定形体。
Near the dry shelf where percolation ceased, the mineral crust hollowed itself into triply-periodic chambers. 灰白土壤在未被占满的虚空中析出骨小梁，靠内部负空间承载压力。It does not conquer the cell; it leaves room for the wind to pass through.
Tested continuous topological homotopy between Bonnet-transformed Schwarz-D and Schoen Gyroid surfaces via implicit potential $F(x,y,z,t) = 0$. Raymarching with a strict low-density threshold kept density variance down to 0.00047. 骨小梁在相变点发生自相似重联，字符直方图集中于 `·` (60%) 与 `:` (26%)，确保了高孔隙率下的几何边界清晰度，未落入实体填充的陷阱。
