struct Provider

Creates resources in one selected backend domain.

Uploads obey that backend’s owner-thread/current-context rules and copy transient CPU data before returning; returned handles do not borrow pixel/vertex storage. Uploaded contents are immutable for retained frames. A changed image or geometry requires a new handle and explicit publication by its owner. There is no generic in-place update, atomic batch, or residency-budget API. Global asset managers permit one active provider/loading owner; constructing another Loader does not create an independent cache/resource domain. Logical shared handles may outlive cache/provider teardown, but native use requires their original live backend domain. Final release follows backend retirement; it is not a promise of immediate native deletion.
