//! The ASCII wordmark the CLI prints when run with no subcommand. It is the
//! same art shown in the README banner, so the banner is literally what you see
//! in your own terminal. ANSI colour is used only when stdout is a TTY and
//! NO_COLOR is unset, so a piped invocation stays plain text.

// "SWAP" and "dex" in the ansi_shadow block font, kept separate so SWAP can be
// coloured violet and dex dimmed - the two-tone family wordmark.
