// Keeps the visitor's address available to route-cached SSR renders.
//
// An app rule such as `'/**': { swr }` renders cached pages from a copy of
// the request without headers. The FAQ API throttles per client address,
// so forwarding only the Nuxt peer would put every cache miss in one bucket.
// The event context is shared with that copy, so the incoming
// x-forwarded-for plus the peer address is recorded here, before the cached
// handler runs, and useFaqApi forwards it.
