Uses only web-standard\n// `Request` / `Response` / `fetch` so it's portable across runtimes.\n//\n// Purpose: chain client → Apps Script → this exit node → destination.\n// Apps Script's UrlFetchApp can't reach Cloudflare-protected sites that\n// flag Google datacenter IPs as bots (chatgpt.com, claude.ai, grok.com,\n// many other CF-fronted SaaS). This exit node sits between Apps Script\n// and the destination; the destination sees the exit node's outbound IP\n// (generally not flagged as Google datacenter) and accepts the request.\n//\n// Setup:\n// 1. Pick a host that runs web-standard fetch handlers (e.g. Deno\n// Deploy, fly.io with a thin server wrapper, or any cheap VPS\n// running Deno / Node + this script as a handler).\n// 2. Paste the contents of this file as the request handler.\n// 3. Set PSK below to a strong secret (`openssl rand -hex 32` from\n// a terminal — DO NOT leave the placeholder in production).\n// 4.
