Noise grid v7 — Pulse field
A bass-like pulse drives both the dot weight and the noise falloff, so the whole field breathes on the beat.
Dots at cell centres, weighted against the converged angle range and scaled by a pulse that also drives the noise falloff — one oscillator moving two things at once, which is what makes it read as a single breath rather than as two effects.
At full pulse the dots grow past their cells and overlap, so each pixel scans its 3×3 neighbourhood and keeps the covering dot drawn last, reproducing the painter's order of the original at any pulse depth.
