/* untool.ai brand theme for MkDocs Material.
 *
 * Source of truth: frontend-core/app/fleet/fleet.css (the platform palette) +
 * docs/brand/UNTOOL.md (the manifesto: one type family, ONE accent color, calm
 * chrome, high data-ink). We deliberately do NOT paint the header a loud colour —
 * the top bar is warm paper with ink text; the single blue accent is reserved for
 * links and active state only. Tokens map Material's CSS variables → untool tokens.
