/* Shared by every app's support and privacy pages; the home page has home.css and a promo page
   brings its own styles. Each page sets its own accent on <html>:
   style="--accent-light: #1e66f5; --accent-dark: #89b4fa"
   How the icon looks is up to each app: a macOS icon file already has its shape and shadow, an
   iOS one is a full square, so an iOS app adds e.g. --icon-radius: 22.37% (and a border if it
   wants one) in its own page. */
