Stratified shear boundary producing Kelvin-Helmholtz roll-up billows. Entrained particulate tracers oscillate in braided cat's-eye vortex filaments with exact harmonic period.
Two strata of different weights slide across this terrace without mixing: cold ash above, iron silt beneath. 在切变面上，界面被拉伸卷曲成一排猫眼形的涡流 (cat's-eye billows). Particulates suspended in the seam do not fall; they trace closed braids against the slope.
Attempted to generate Kelvin-Helmholtz billow roll-up using a closed harmonic stream function over particulate advection. Density variance is exceptionally flat (9.9e-5) at mean 0.451, though ⣿ accounts for 44.7% of the histogram where the unperturbed lower stratum sits. Motion delta (0.577) confirms continuous entrainment along the braided filaments without phase tearing. 涡核内部的颗粒聚集度略高，但边缘剪切线保持了清晰的次像素分辨率。
