   Device Cloud — site design system

   Inherited from the app's own palette (Resources/Styles/Colors.xaml,
   theme name "Signal"). Its one law is carried onto the web intact:

       indigo carries the chrome, cyan marks anything live.

   So the icon chips here are two-tone, not a rainbow: indigo for a
   surface or a capability, cyan for anything that is a radio, a
   listener or an address. The signature element is the STATUS SPINE —
   a 3px rail down the left of a card, inert until hover, cyan on the
   things that broadcast. Colour stays scarce, which is the only
   reason it stays legible.
