/* Build a Property Website
   RIZE Property page builder

   Colours and type are the RIZE brand kit, the same set the property pages use.

   Built for a phone held in one hand in a driveway. Nothing here asks anyone to
   write anything. Every screen is taps, a number, or a date. Portrait first,
   widens once at 720px. */
