+Outbound requests to Microsoft are optionally routed through a Cloudflare Worker (`cloudflare-worker/worker.js`). This distributes requests across Cloudflare's global edge IPs instead of a single server IP, preventing Microsoft's rate-limit block (error 715-123130) under high traffic. The Worker is opt-in via environment variables — omit them to go direct to Microsoft.

 ## Deployment
 
-> ⚠️ **Deploy the backend to a standard VPS** (Hetzner, DigitalOcean, Linode, etc.) — **not** serverless platforms like Vercel, Cloudflare Workers, or AWS Lambda. Microsoft rate-limits known datacenter IP ranges.
-
 Recommended setup:
 
 | Component | Platform |
 |---|---|
 | Frontend | Cloudflare Pages / Vercel (static) |
-| Backend | VPS with a non-datacenter IP |
+| Backend | VPS (Hetzner, DigitalOcean, Linode, etc.) |
+| Outbound proxy | Cloudflare Worker (optional, recommended for public instances) |
+
+> ⚠️ **Deploy the Go backend to a standard VPS**, not serverless platforms. The Cloudflare Worker is used only as an outbound proxy for Microsoft API calls — the backend itself must be a long-running process with session state.
