1//! Engine-side caches for GPU resources derived from a scene.
2//!
3//! Each cache turns a recurring, expensive-to-derive scene input into a bounded,
4//! reusable GPU resource, and is maintained at the frame boundary rather than
5//! mid-frame so handles handed out during encoding stay valid for that frame.
6//! [`retained`] is the one whose input is a rendered body rather than a decoded
7//! resource: a `PushRetained` bracket's pixels, kept so a later frame's
8//! `DrawRetained` composites them instead of painting the body again.
