//! Central terminal-UI vocabulary for tokenix's human-facing output.
//!
//! Every command that a person reads (help, doctor, gain, stats, filter) renders
//! through these helpers so the visual language stays consistent: one box style,
//! one progress-bar scheme, one set of semantic colors. The `colored` crate
//! auto-disables ANSI on non-TTY / `NO_COLOR`, so all of this degrades cleanly
//! when piped. LLM/JSON output (query, graph) deliberately does NOT come through
//! here — that is a token contract, not a display surface.
