+- **Network operations are disabled by default**. Use `--enable-network-download` to download missing audio files.
+- Pass Wi-Fi credentials via `--ssid` and `--password` CLI flags (or SSID/PASSWORD environment variables) to auto-enable network download.
+- If audio clips are present locally, the test runs without any network operations (offline-capable).
+- If clips are missing and network download is disabled, the test will SKIP with a helpful message.
 - You can override default network probe targets using NET_PROBE_ROUTE_IP and NET_PING_HOST to avoid connectivity-related failures in restricted environments.
