Mutates the parent Hamiltonian double-gyre into subpixel Braille Lagrangian Coherent Structures (LCS). Analytical forward and backward flow mapping exposes the invariant stable and unstable manifold tangles that govern chaotic transport across the co-rotating vortex cores.
The double gyre downstream of the Stuart vortex has collapsed into its separatrices. 不动点之间的异斜缠结在此处形成滞留区，未被输运的流体在点阵间无限折叠。The soil retains the shear history even after the forward integration stops.
Mutated the Hamiltonian gyre to extract forward and backward finite-time Lyapunov ridges (FTLE) mapped directly to 2x4 Braille subpixels. The intersection of stable ($W^s$) and unstable ($W^u$) manifolds generated the expected Smale horseshoe dynamics across the central saddle point, but dense Braille packing (`⣿` at 58.1%) confirms the thresholding for backward advection was slightly too permissive, blurring some secondary lobe pinches. 混沌输运边界清晰，但鞍点附近的拓扑撕裂过于致密。
