/**
 * NanoClaw brand palette for the terminal.
 *
 * Colors pulled from assets/nanoclaw-logo.png:
 *   brand cyan  ≈ #2BB7CE  — the "Claw" wordmark + mascot body
 *   brand navy  ≈ #171B3B  — the dark logo background + outlines
 *
 * Rendering gates:
 *   - No TTY (piped / redirected) → plain text, no ANSI
 *   - NO_COLOR set               → plain text, no ANSI
 *   - COLORTERM truecolor/24bit  → 24-bit ANSI (exact brand cyan)
 *   - Otherwise                  → kleur's 16-color cyan (closest fallback)
