/* The workspace date picker. Built entirely from the tokens app.css defines, so
   the dark theme and the future layout come for free rather than being repeated
   here. app/static/js/datepicker.js is what puts these elements on the page.

   The field keeps the shape of every other input in the app — the same border,
   radius and focus ring — because it is still a field you type into. Only the
   calendar that opens is ours, and it is one of the few things in this app that
   legitimately floats: it is a popover, so it carries --shadow-pop. */
