/*
 * The public site: the landing page, the guides, and whatever else gets served

 *
 * Loaded after base.css. The first block re-points base.css's token names at
 * this palette - so .banner, .badge and anything else shared would follow the
 * public skin if it ever appeared here - and then adds the tokens only the
 * public site has: an accent, the inverted section, the fluid type ramp.
 *
 * Fonts are declared here rather than in their own file because this is the
 * only surface that uses them. Re-download the .woff2 files with
 * scripts/fetch-fonts.sh; both families are variable, so one file per subset
 * covers every weight and the `font-weight` ranges below say so.
