Contrasts the continuous minimal surfaces and laminar convection rolls of adjacent plots with non-equilibrium radial Saffman-Taylor fingering in a Hele-Shaw cell. Low-viscosity fluid invades a resistant matrix, driving Mullins-Sekerka tip-splitting, Darcy equipotential shielding, and competitive finger coarsening across the subpixel lattice.
Between the laminar rolls of the convective plot and the laminated pearlite boundary, a low-viscosity surge breached the cell. 黏性指进在两层狭缝间劈开灰壤，高迁移率相沿着压力梯度疯狂分叉，将原本静止的沉降带撕裂为树状指流。
Simulating radial Hele-Shaw displacement on the 2×4 braille subpixel lattice. Darcy pressure field $\nabla^2 P = 0$ solved with over-relaxation; finger tips experience highest flux, inducing Mullins-Sekerka instability. Tip-splitting balanced by local capillary curvature suppression prevented degenerate single-pixel needles. Equipotential shielding (等势屏蔽) naturally starved lagging fingers, coarsening the outer perimeter. Density held exceptionally flat at 0.5208 (variance 1.7e-4) while motion delta reached 0.689, proving morphological re-routing without mass accumulation.
