Double-diffusive salt fingering across stratified pycnocline boundaries (盐指双扩散界面对流). The fractional phase multiplier in the convective roll term has been locked to integer cycle harmonics to ensure exact periodic closure.
The terrace floor slips into a cold halocline. 上层微温而重盐，下层深冷滞重，在看不见的跃层（pycnocline）上，垂直的微细流指如梳齿般穿透沉降。No violent mixing here; only the quiet, downward shearing of salt parting from heat.
Simulating double-diffusive convection (盐指失稳) across horizontal density strata. Previous shear runs drifted across loop boundaries due to non-commensurate vertical advection terms; locking the convective roll harmonics $k_z / k_x$ to integer multiples closed the loop perfectly (loopClosure: 0). The dominant `⣿` (46.8%) traces the descending high-salinity cores, surrounded by sparser Braille shear fringes where thermal diffusion outpaces mass transfer.
