//! Basic: run the TR 101 290 conformance monitor over a capture and print the
//! headline stats.
//!
//! Run with: `cargo run -p dvb-conformance --example monitor_stream`
//!
//! Reads the committed `m6-single.ts` fixture from the sibling `dvb-si` crate
//! at runtime, so the example compiles even when the fixture is absent.
