//! Keccak hasher.
//!
//! The [`round`] chiplet (TAM-style miniVM running one Keccak-f\[1600]
//! round), the [`sponge`] chiplet that absorbs / squeezes around it,
//! the [`node`] chiplet that ties chunks + sponge into a Keccak
//! transcript-DAG node, and the [`mod@reference`] implementation used as a
//! trace-gen oracle. Connects to the shared
//! [`memory64`](super::memory64) bus and consumes input chunks from the
//! [`chunk`](super::chunk) chiplet.

//! See the design notes, the design notes, and
