/* Material for MkDocs, wearing the Unchained Labs brand.
 *
 * The brand fonts are loaded here rather than through Material's own `font:`
 * option, because the palette needs three faces — display, body and mono — and
 * Material only wires up two. Declaring them in tokens.css without loading them
 * (which is what shipped first) silently falls back to system sans, so the site
 * renders in the wrong typeface while looking like nothing is wrong.
 *
 * Everything below maps Material's custom properties onto the tokens in
 * tokens.css. No hex value is written in this file: the branding repo is
 * explicit that colours live in one place, so a palette change stays a
 * one-file swap rather than a grep across seven sites.
