1//! `celestial/chunk-scatter-compact` — CEL-73 scatter draw-list build. One
2//! thread per cached pool candidate of each VISIBLE chunk, per layer: gates by
3//! the LIVE `density`/height sliders and appends surviving transforms into
4//! the layer's indirect MultiMesh (count into the command buffer — no
5//! readback). This is the ONLY GPU work a slider edit re-runs.
