/* docs/stylesheets/theme.css: the site takes its colours from the banner.
 *
 * banner.svg is navy (#14212d) with the wordmark in cream (#fbf4e4), the
 * tagline and the clock's bells in gold (#e6b84a) and the clock's ring in red
 * (#c7372f). The header and the dark page are the navy, the text on the header
 * is the cream (14.9:1), and links are the gold: as is on the dark page
 * (8.8:1 on #14212d), darkened to #8f6b14 on white (4.9:1). mkdocs.yml sets
 * `primary: custom` and `accent: custom`, so Material paints nothing until
 * these variables exist.
