Variable: PINNED_ADDRESS

Non-standard init key carrying the SSRF-validated address the connection must be pinned to. The built-in transport uses it directly; an injected fetchImpl receives it on its init object and must honour it to stay rebind-proof — pinnedFetch does, so a wrapper that delegates to it keeps the pin.
