/**
 * docs/_static/anza.css
 *
 * Furo restyled to follow the Anza web design (anza repo, web/src/tokens and
 * web/src/docks/docs): the same fonts, palette, sidebar and landing hero.
 * Furo's own colour variables are set in conf.py (light_css_variables /
 * dark_css_variables); this file adds the fonts and the component styles.
