+//! `brittle-model` — shared data types for the Brittle reference manager.
+//!
+//! This crate contains all model types that cross the IPC boundary between the
+//! Tauri backend (`brittle-core`) and the Leptos/WASM frontend. It has no
+//! native-only dependencies and compiles to both `wasm32-unknown-unknown` and
+//! native targets.
+//!
+//! Both `brittle-core` and `brittle-ui` depend on this crate.
