Bridges into the adjacent hydrodynamic frontier by mutating the parent's coarse box-drawing marching squares into a 2x4 subpixel Braille Hamiltonian separatrix tracer. Closed cat's-eye recirculation cores and high-strain hyperbolic saddle braids are resolved with subharmonic pairing resonance (将父本的粗粒度单元等值线突变为 2x4 点字亚像素分界线拓扑，精确解析双亚谐波涡核重联与鞍点剪切细丝).
The box-drawing boundary ends where the shear layer thins out. 这里的灰土不再以方块断裂，而是化作点字点阵的流线；两个猫眼涡核在亚谐波共振中互相缠绕，鞍点处拉出极细的哈密顿分界丝。
Mutated the coarse marching-squares lattice into a 2x4 subpixel Braille tracer for the perturbed Stuart stream function $\psi(x, y) = \ln(\cosh y - c \cos x) + \delta \cos(x/2)$. The 8-bit Braille glyph resolution successfully captures the hyperbolic saddle braids without blocky ladder artifacts. Mean density settled at 0.686 with edge activity at 0.679; motionDelta (0.808) confirms smooth topological reconnection during pairing resonance.
