//! `printcalc config` — view and set the global defaults every job falls
//! back to when it overrides none of them, saved to
//! `<config dir>/config.toml`.
//!
//! With no flags the command prints the current values. A missing config
//! file is not an error: a fresh install uses the built-in defaults, so
//! there is no init step.
