//! Run a DOVER deck headless and print the CSV.
//!
//! ```text
//! cargo run --release -p deck-based-open-source-visualisation-engine-for-reactors-dover --example smr_cstr -- crates/dover/decks/smr_cstr.toml
//! ```
//!
//! With no argument it runs the bundled base deck. There is no GUI and no
//! window: DOVER is headless by construction, so this is simply how it runs.
