+//! # llimphi — native Rust UI framework (2D **and** 3D)
+//!
+//! Sovereign, retained-mode UI framework with an Elm-style loop
+//! (`input → update → view → layout → raster → present`), built on
+//! `vello` + `wgpu` + `taffy` + `parley`. This is the **facade** crate: it
+//! re-exports the core ([`ui`]) plus the [`theme`] tokens and the 3D
+//! [`engine3d`]. For widgets and modules, add the individual
+//! `llimphi-widget-*` / `llimphi-module-*` crates.
+//!
+//! ```no_run
+//! use llimphi::{App, View, Handle}; // re-exported from llimphi-ui
+//! ```
+//!
+//! - **Core / Elm loop, `View<Msg>` DSL:** [`ui`] (`llimphi-ui`).
+//! - **Theme tokens & palettes:** [`theme`] (`llimphi-theme`).
+//! - **3D voxel + mesh engine:** [`engine3d`] (`llimphi-3d`).
