//! Operators that mix channels: each output channel is a weighted sum of input channels.
//!
//! - [`car`]: common average and common median reference (subtract the mean or the median over
//!   channels at every sample).
//! - [`SpatialWhitening`]: ZCA whitening, global or over each channel's nearest contacts.
//! - [`SurfaceLaplacian`]: each channel minus the (distance-weighted) mean of its neighbours (HD-EMG,
//!   ECoG grids).
//! - [`sparse`]: the `[channels, channels]` matrix behind whitening and the Laplacian, applied dense
//!   or as sparse rows (CAR has its own single-pass kernel).
