+//! The top-level entry point for the wsg-lib crate. Exposes eight public modules organized by architectural responsibility:
+//! **app** (App facade + AppBuilder), **handler** (AppHandler trait), **core** (Manager + Executor + geometry types),
+//! **mesh** (geometry sources: primitives + import), **resources** (data types), **pipeline** (shader compilation cache),
+//! **scene** (resource graph and entity management), **prelude** (glob re-exports), and **utils** (configuration and error handling).

 //! ## Module Interaction Map
 //! - `core` consumes resources from `resources`, pipelines from `pipeline`, and errors from `utils`.
