1//! `celestial/chunk-scatter-place` — CEL-73 scatter placement dispatch. One
2//! thread per candidate of each realize-batch chunk, per layer. Runs only when
3//! chunks were (re)realized (`realize_count > 0`); the pool it writes is CACHED
4//! per slot, so camera moves and density/height edits never re-run it.
