//! Tiny color palette for CLI output. Centralized so adding a new service
//! status (or a new prefix) forces a decision about its color, instead of
//! drifting into "some lines colored, some not."
//!
//! Sticks to the 16-color ANSI palette — works on every terminal, no
//! terminfo lookups, and `console::style` auto-disables when stdout isn't
//! a TTY or when `NO_COLOR` is set.
