//! Engine-handle types for the four major state singletons.
//!
//! These are the async-machinery halves of the engine/value split described in
//! the props modules.  They own JS object handles, draw locks, async
//! subscriptions, and PubSub channels — i.e. anything that cannot be cheaply
//! cloned into a plain `PartialEq` prop.
//!
//! **Current status (Step 3 of the migration):** Each `*Engine` type is a thin
//! type alias for the existing `Rc<*Handle>` wrapper.  They will be replaced
//! with true struct types in later migration steps once the component tree has
//! been updated to consume value-semantic props instead of the old handles.
