// Beta end-to-end verification test.
//
// Runs the full Dart → FRB → Rust → tsclientlib → cn.teamspeak.app
// path, including the audio engine. Verifies:
//   1. Connect + snapshot still work (Alpha regression).
//   2. Audio engine starts.
//   3. PTT toggles successfully.
//   4. Encoder produces Opus frames while PTT is held.
//   5. Disconnect cleans both protocol and audio.
//
// Network-dependent. Quietly tolerates a server that rejects voice
// (e.g. because the test account is not yet allowed to talk).
