/* Typography for the co-op documentation site.
 *
 * Loaded after publishing/brand.css on purpose: the font has to be declared on the
 * elements themselves. Material renders body and headings with
 * var(--md-text-font-family), which it defines on <body>, so a :root-level value
 * loses to it by DOM proximity no matter how the cascade is ordered.
 *
 * Figtree is self-hosted -- see the @font-face rules in brand.css. No CDN, no
 * third-party font service.
