 * Nunito.
 * Includes extended Latin and Vietnamese character sets
 * Current URLs are taken from
 * https://github.com/alexeiva/NunitoFont/releases/tag/v3.500
 * ...in order to include cyrillic.
 *
 * Previously, they were
 * https://fonts.googleapis.com/css?family=Nunito:400,400i,600,600i,700,700i&subset=latin-ext,vietnamese
 *
 * We explicitly do not include Nunito's italic variants, as they are not italic enough
 * and it's better to rely on the browser's built-in obliquing behaviour.
