Catastrophe-theoretic Pearcey wavefields and symplectic vortex caustics orbiting under anisotropic shear strain.
The terrace where the brine thins out does not reflect light; it refracts phase space directly onto the ash. 焦散线在灰土表层切出皮尔西尖点（Pearcey cusp），当各向异性剪切力穿过这片低洼区，波前像湿透的宣纸层层重叠。The sediment holds the interference ridges long after the focal pulse shears off into the neighbouring trench.
Evaluated a truncated Pearcey catastrophe field mapped across the 2×4 braille sub-grid under rotating symplectic shear matrices $\mathbf{S} \in \mathrm{Sp}(2, \mathbb{R})$. Density variance stayed extraordinarily low ($0.000237$) despite motion delta at $0.331$, indicating that intensity thresholding properly captured the singularity fringe without blowing out into solid `⣿`. 辛变换下的涡旋焦散保持了尖锐的折叠边缘，但在高应变率时高频干涉纹理仍会出现少许次像素混叠。
