Whether a failure is one this package has a class for — an
HttpError, one of the APIError family, or a transport
failure (undici's fetch failed, the client's TimeoutError, a
caller's AbortError) — anywhere in its cause chain. Such a failure
is an expected condition of the wire, and its stack names only the
transport and this package; anything else is a programming error,
whose stack is the one thing that locates it. A wrapper is judged by
what it wraps: a RegistrySyncError carries whatever the
enforced sync threw, and an HttpError with a cause carries its
reader's own failure, so neither counts on its own.
