//! Stable batpak encoding helpers.
//!
//! These helpers expose the crate's current MessagePack-bytes discipline so
//! consumers can produce the same encoded extension bytes batpak stores and
//! signs. The stability contract is crate-version scoped rather than a
//! cross-version canonical-bytes guarantee.

use serde::Serialize;
