/* ==========================================================================
   COUNTDOWN CLOCK — styles
   Pairs with assets/js/countdown.js. Switched on via sections/countdown.html.

   COLORS ARE NOT IN THIS FILE. Like the rest of the site's stylesheets, the
   color block below just forwards to assets/css/theme.css — the --countdown-*
   names. Change them there, not here.

   Everything else (sizes, corners, spacing) is a variable in the block below,
   and every rule past it is scoped under .pbc-countdown, so nothing in this
   file can affect the rest of the page.

   Full documentation, plus a live demo you can open in a browser, is in
   countdown-kit/ — README.md and demo.html.
