   FAHRSCHULPORTAL: /desktop — die Desktop-App „FahrschulPortal Büro“
   ==========================================================================

   After /styles.css, /brand.css, /landing.css (header, footer, buttons,
   icons, the two app windows: .ln-desk-stage) and /legal.css (.pg-hero).
   Markup: src/lib/desktop-page.js. Script: js/desktop.js.

     .dk-get      the file for this computer, under the title
     .dk-feats    what the app does, six short entries
     .dk-files    every file: label, size, name, SHA-256 with a copy button
     .dk-cmds     the two commands that check a download

   Black page, hairlines, no boxes lifted to grey. The one white button is
   the download (or, before the release, the access request). Colour only
   as state — and on this page there is none. Checksums and commands are
   mono, they are meant to be compared character by character. Prefix `dk-`. */
