ReadonlyuLine data texture node (RGBA32F, 6 texels/segment). Rebound per
node by the wrapper's updateLineTexture (fresh node + rebuild).
ReadonlyuReadonlyuReadonlyuReadonlyuActive ordering buffer: 0 = aSortedIndex, 1 = aSortedIndexB.

Pre-created TSL leaf nodes supplied by the wrapper class. Same pattern as
PointPickTSLNodes/GSplatPickTSLNodes: consumers own theUniformNodes and the factory references them directly, avoiding the.onUpdate('render')callback churn.
