+// Installs the HTTP-layer host rewrite: hooks BestHTTP.HTTPManager.SendRequest(HTTPRequest) and
+// rewrites the request's Uri (ns.rec.net -> ns.recflare.net) so the URL, TLS SNI and Host header all
+// carry the target host -- a genuine request to the alternate backend, not just a redirected IP.
+// Waits for the il2cpp runtime; safe to call on its own thread. No-op if no rewrite pairs configured.
