/* ==========================================================================
   Components — panels, controls, cards, tables, charts, feeds

   Two rules govern colour here, and they are worth stating because every
   decision below follows from them:

   TEAL is the colour of the system working — active states, primary actions,
   live routes, anything the software is doing on your behalf.

   GOLD is the colour of significance — an optimised result, the winning
   number in a comparison, the selected thing. It is deliberately rare. If
   every card had a gold edge, gold would mean nothing.

   Everything else is white, hairline borders and deep navy type.
