Kelp forest — the t axis, made physical

Every frond is a strip of segments, each bent by the field velocity sampled at its own height and at the current field time — field.sampleUW(x, y, z, out, t). Nothing here is keyframed: the sway is the library's own churn, the Kolmogorov-scaled time evolution, so tip wisps flutter faster than the base leans. Turn churn to 0 and the whole forest freezes mid-current; raise coherence and the stalks start leaning together in coherent gusts. Drag to orbit, scroll to zoom.
