Type Alias AssetClosures 

pub type AssetClosures = Rc<EngineCell<Vec<Closure<dyn FnMut()>>>>;

A reference-counted, shared-mutable list of asset load callbacks.

Stores Closure objects to prevent them from being dropped prematurely, avoiding memory leaks when registering onload/onerror handlers.

Held behind EngineCell (an UnsafeCell-backed Sync newtype) rather than RefCell so the storage matches the rest of the engine’s static mut convention. Access via EngineCell::get_mut to obtain the underlying Vec for push / clear operations.
