//! Slint backend for A2UI.
//!
//! Translates an A2UI component tree (the flat `id → ComponentModel` map owned
//! by [`a2ui_base::model`]) into a Slint reactive tree and bridges Slint UI
//! events back to the framework-agnostic interaction layer in `a2ui_base`.
//!
//! Unlike the ratatui backend (immediate-mode painting on a character grid),
//! Slint is retained-mode + declarative: layout is handled by Slint's engine,
//! so this backend does **not** reproduce the tui's measure pass or
//! `layout_engine`. Instead it walks the component tree into a [`live_tree`]
//! model that `.slint` components bind to reactively.
//!
//! Everything here lives behind the `backend` cargo feature, which pulls in the
//! Slint runtime. Without it this crate is an empty shell (it compiles with no
//! dependencies beyond `a2ui-base`), keeping the workspace's default build light.
