1//! `Defer` over `tokio::spawn` (architecture section 5): work that
2//! outlives the response, the native counterpart of
3//! `worker::Context::wait_until`.

8/// Spawns deferred work on the tokio runtime. Request-scoped through the
9/// [`Scope`](cratefield_core::Scope) like every defer — the runtime holds
10/// no state of its own.
11///
12/// The spawned task is detached: a panic inside it is tokio's default
13/// panic-and-drop (the join handle is not awaited, exactly like a
14/// fire-and-forget `wait_until` on Workers). Handlers that need errors
15/// observed do the observing themselves before deferring.
