// Pre-routing proxy contract — application-owned global request policy
// (engine spec §4/§5). One responsibility per file (AGENTS.md §1).
//
// The proxy runs *before* route selection. The engine wires the plumbing
// (the Tower service that actually rewrites the request before the Axum
// router sees it — see `service.rs`); the application owns only the policy,
// expressed as a pure function from [`Request`] to [`Action`].
