/* ===================================================================
   ZONE GROUP SMART & AUTOMATION
   -------------------------------------------------------------------
   THE RULE OF THIS PAGE: nothing moves until it is triggered.

   Its sibling site, Zone Real Estate, is liquid — everything drifts
   all the time, and it overshoots when it lands. A building system is
   the opposite: it sits still, waits for a trigger, propagates along a
   path, then settles exactly. So here the easings do not bounce, the
   ambient layer is a plan grid that does not move at all, and every
   animation is a response to something — a scroll, a pointer, a tap.

   PALETTE is fixed by the brand:
     background #100D18   surface #19142A   primary #876CFF
     secondary  #48D4E8   text    #F4F1FF
   Every colour below is one of those five or a derivative of them.
