//! Betamax command-line entry point.
//!
//! The binary intentionally delegates core behavior to the library crate. CLI modules should handle
//! argument parsing, source loading, and presentation; parsing, execution, rendering, and media
//! writing belong in library modules where they can be tested directly.
