Combined with early auth, a strict per-client 2 s rate limit, 5000-char cap, and voice allowlist, the blocking cost is bounded and intentional. All audio chunks are buffered before sending so that a Content-Length header can be included. The 5000-char cap bounds audio to roughly 1-5 MB, making full buffering safe. Without Content-Length the HTTP/1.0 server leaves the response open until a ~31 s timeout fires, and the browser cannot play the blob mid-stream.
