//! Statistical transforms: aggregation that runs before scales see the data.
//!
//! Every aggregator here is a mergeable monoid — two partial results combine
//! associatively via `merge` — so host-side parallel chunking (over a fixed
//! reduction tree) and streaming increments are compositions, not features. The
//! plot pipeline inserts [`m4`] automatically for large line layers; everything is
//! also public API for direct use.
