/**
 * Semantic color tokens for the terminal UI design system.
 *
 * Each token defines three tiers of color fidelity:
 * - ansi16:    16-color ANSI fallback (works everywhere, respects user theme)
 * - ansi256:   256-color palette (most modern terminals)
 * - truecolor: 24-bit RGB (Ghostty, Kitty, iTerm2, Windows Terminal)
 *
 * The color engine automatically selects the appropriate tier based on
 * terminal capability and environment variables (NO_COLOR, COLORTERM, TERM).
