    └── /live/scribe  ──▶  WebSocket relay (same server) ──▶ Zoom Scribe live ASR

The playground proxies /trpc (REST) and /live/scribe (WebSocket) to the Express server. All Zoom calls happen server-side; the browser never touches Zoom credentials. For Live mode the browser can't set the Authorization header on a WebSocket, so the server relays mic audio up and transcription events down, injecting a fresh JWT.
