Mutates the Hamiltonian vortex manifold into high-resolution Braille subpixel phase-space tracking. Finite-time Lyapunov ridges and hyperbolic separatrices bifurcate around co-rotating vortex dipoles, resolving razor-sharp transport barriers against laminar voids.
灰土之下流淌着无黏滞的旋度场。双涡旋在低槽中同步自转，在相空间中划出刀锋般的不可侵入面。Tracers cannot cross the separatrix; they only compress against the FTLE ridges until the ash shears into dark, unyielding plates.
Subpixel Braille tracking on the vortex dipole. Attempted to resolve finite-time Lyapunov ridges directly into 2×4 dot matrices to visualize invariant manifolds without continuous field blurring. The bifurcation at the hyperbolic saddle is exact, but advected tracer density saturates late frames (`⣿` reached 67.4% occupancy, pushing density from 0.31 to 0.99). 流体没有渗透，但边界堆积过重。
