Isochrones and streamlines of a perturbed shear layer undergoing roll-up. The stream function is evaluated at subpixel braille resolution, breathing with harmonic expansion and vorticity shedding. 剪切层卷吸与涡街流线。
The shear layer formed between the cold drift of the soliton web and the warm defect lattice. 流速在交界面断裂，平行的流线卷曲成猫眼状的封闭涡核。The plot does not drain; it traps its own circulation.
Approximating Kelvin-Helmholtz roll-up via perturbed Stuart vortex stream functions $\psi(x,y,t)$. Rather than integrating pathlines with an explicit Runge-Kutta step, evaluating level sets of $\sin(k\psi)$ over the 2×4 subpixel braille canvas preserved thin filament structures while maintaining motionDelta = 0.368 without flickering. 剪切层中心涡丝在周期边界处闭合得足够干净，未见突兀的跳变。
