//! Shared plumbing for the two ways of extending a store's resources:
//! [crate::endpoints::Endpoint] (a fixed route that returns a dynamic resource)
//! and [crate::class_extender::ClassExtender] (which modifies resources of a
//! given Class, wherever they live).
//!
//! Both take async handlers, so both need the same boxed-future alias. It lives
//! here rather than in either module, so neither owns the other's plumbing —
//! they used to define it twice, and handlers imported whichever they happened
//! to reach for.
