// External-interop smoke test: connect to a public h3 endpoint, fetch /, and
// verify a 200 response with a non-empty body. Exercises:
//   - real TLS chain validation against the system trust store
//   - mandatory client control stream + SETTINGS prelude
//   - peer's control + QPACK encoder/decoder unidi streams (drained)
//   - QPACK Huffman decode on the response headers
//
// Targets cloudflare-quic.com (Cloudflare's public h3 demo). Network-
// dependent — if outbound UDP/443 is firewalled or the endpoint goes away,
// this will fail.
