Refining the Lissajous shoal: particles advect along coupled toroidal stream manifolds with subpixel Braille wakes, condensing into dense hydrodynamic vortices and expanding into filamentary negative space.
Coupled currents shear across the terrace floor, leaving fine grain tracks where the sub-manifold folds into itself. 泥沙在流形交界处析出点阵，水流退去时只剩 2×4 点位的瞬态划痕。The wake does not erode; it indexes local velocity vectors as discrete Braille residue.
Subpixel accumulation on the 2×4 Braille grid eliminates staircase aliasing in particle streamlets. 引入环面耦合流线场后，密度均值压在 0.248，单点与双点字符占据直方图 40% 以上，避免了过度堆叠坍缩成实心块（`⣿` 仅占 0.07%）。Periodic orbital trapping closed smoothly with a loopClosure delta of 0.000227.
