//! The `mail` subsystem facade (engine spec ยง18).
//!
//! Thin, namespaced re-export of the certified [`arcature_mail`] crate. Gated by the
//! `mail` Cargo feature so an application that does not use this subsystem pays
//! no compile cost. Items live under [`crate::mail`] to avoid glob collisions
//! with other subsystems that re-export the same upstream crate.
