/* ---------------------------------------------------------------------------
   Ember Studio by NexaBlack - one stylesheet for the marketing site, the
   app and the admin console.

   The tokens are taken from thenexablack.com so the product reads as part of
   the same company: Audiowide for display type over Red Hat Display, the
   #f93c10 signature red on stacked near-black surfaces, and hairline borders
   in translucent white rather than solid grey. Dark by default; the light
   theme keeps the red.
