/* ==========================================================================
   DIE APP — fahrschulportal.com/die-app (/iphone, /android)
   ==========================================================================

   After /styles.css, /brand.css, /landing.css and /phone.css: header, type,
   buttons, reveals, marquee, closing and footer are the landing page's, the
   device is phone.css. This file is the page around it.

   One page, three looks: <body data-platform="ios|android|desktop">, chosen
   by the server from the User-Agent (src/server.js) and corrected by the
   script for iPadOS. `data-only="ios desktop"` shows an element for those
   platforms only; the phones follow the platform by themselves.

   Motion, in the house style: things enter with --ease-out, move with the
   drawer curve (--da-glide), nothing bounces that nobody threw. Everything
   that moves is transform, opacity, filter or clip-path, and stops under
   prefers-reduced-motion.

   No brand hue, as on the landing page: the rings, the money and the chips
   are greys. The only colours are the screenshots and the official badges.
   Prefix `da-`.
