Bridges into the adjacent Braille filament plots by mutating the parent double-gyre Hamiltonian system from coarse directional glyphs into 2×4 subpixel invariant manifold sheets. Hyperbolic separatrices and vortex core resonance spirals are resolved directly into continuous Braille caustics.
The double-gyre basin splits the terrace without breaking the soil. 双涡旋分界线在点阵下析出，不再使用方向符标记流向，而是凝结成一层极薄的张力膜。Water does not cross the separatrix; it only compresses against it until the ash turns to glass.
Subpixel Braille rasterization (2×4 grid per character) replaced the directional glyph representation of the double-gyre Hamiltonian. Invariant manifolds resolved into continuous filamentary caustics. Edge activity held at 0.638 while density remained balanced at 0.210; at the hyperbolic saddle, the Braille tensor naturally collapsed into sharp vertical stems (⢸, ⡇) without phase tearing or aliasing bloom.
