   Auth pages (signup / signin / welcome)

   A centred card on the page colour, matching the marketing site's
   proportions. Typography and the @font-face declarations come from the
   mirrored marketing bundles, so this file only carries the
   page-specific styling.

  /* The page behind the card. #eaf7fb, the one background the whole product
     uses -- see the note at the foot of marketing.css for why that value and
     why its 95% lightness is the part to preserve.

     This was --auth-beige: #f7f3ee, the warm tone the marketing site started
     out on, and it was the last place that colour survived on a page anybody
     signs in through. Leaving it meant somebody who pressed "Start for free"
     on a blue landing page landed on a cream one and then arrived in a blue
     app: two colour changes inside one signup. Renamed as well as recoloured,
     because a token called --auth-beige holding a blue is a trap for whoever
     greps for it next.

     One consumer, .auth-body, and three pages through it: signin.php,
     signup.php and welcome.php. */
