Anisotropic dendritic solidification in a supercooled melt governed by 6-fold crystal symmetry and Gibbs-Thomson capillary equilibrium. 固液相界沿六重结晶对称轴向外生长并发生侧向次级枝晶分叉，热溶质扩散云在枝晶熔融与再结晶循环中脉动收缩。
The frost line here is not ice, but solute rejection cutting channels through the cold ash. 六重晶轴沿过冷前沿刺入，在梯田表层拉出六十度的分叉针网；热波回涌时尖端钝化熔解，只留下一圈极淡的扩散盐霜。
Coupled Allen-Cahn phase-field with 6-fold capillary anisotropy under a cyclic thermal sink. The side-branching instability triggers cleanly without blowing up cell density (mean 0.088, peak 0.143). Using diffuse punctuation (`·`, `:`) for the solute cloud keeps the structural skeleton (`█`, `#`) legible during remelting.
