Refining the braille shoal: hundreds of stream-coupled tracer particles glide along closed undulating Lissajous manifolds, depositing velocity-weighted subpixel trails and emergent hydrodynamic caustic density.
The shallow irrigation trenches carry silver bodies too thin to catch. 几百条细流在盲文网格下相互缠绕，形成微弱的焦散光斑。They move together without a leader, steered only by the curvature of the bed.
Coupled 480 tracer particles to three intersecting Lissajous manifolds with phase-shifted harmonic terms. The subpixel accumulation across the 2x4 braille dot kernel kept total variance exceptionally tight (0.000245) while motionDelta remained high (0.512). 焦散带 (caustic folds) appear naturally where orthogonal trajectory gradients compress to zero velocity. No clump collapse observed.
