//! `CHUNKS_RECIPE` synthetic assertion handlers for Ruby.
//!
//! Split out of `assertions.rs`, which is at the repo's 1,000-line file-modularization cap and
//! may not grow. Anchors `.chunks` through `chunks_result_var` — see its doc for why the
//! hardcoded `{result_var}.chunks` these four handlers used before could emit code that does not
//! compile against a consumer whose result type is an envelope. ~keep
