 1. A k8s pod sends an HTTP request to `http://<proxy-vm>:8080/elevenlabs/v1/text-to-speech/...` with the `X-Proxy-Token` header and the original API key.
 2. Nginx checks the source IP against `ALLOWED_CIDR` and validates `X-Proxy-Token` — rejecting with 403 if either fails.

 4. `X-Proxy-Token` and all IP-leaking headers are removed before forwarding; API keys pass through unchanged.
 5. The response streams back unbuffered to the pod — critical for binary audio data and long-polling (Telegram).
