/* assets/css/auth.css
   Split canvas for sign-in, sign-up and sign-out.

   The left panel is not decoration. It carries the one claim the product has to
   land before someone will type an email address: their current numbers are
   wrong in two directions at once. A gradient and a logo would waste the most
   valuable space on the page. */
