   PHONES AND TABLETS (≤900px): the daf view as a reading app.
   A title bar on top (the shelf, the daf's name, which opens a
   picker, the star, profile and settings), the daf's tools in a
   dock at the bottom, both tucked away while reading down the
   page. The explanation is a bottom sheet that rides on the
   keyboard. Loaded after style.css and ui.css, so it wins over
   both; the look (type, fields, the sheet's parts) is ui.css's.
