//! JSON API types for Engine boundary documents.
//!
//! Types reachable from [`crate::Engine`] carry no JSON-shaping serde attributes
//! and no custom serde except exact scalar codecs (rationals, date/time strings,
//! decimal strings). JSON shape for `show` / `run` / SDK documents lives only in
//! `lemma::api`.
