   VICC v63 — design system

   LAYOUT THESIS
   The v61 UI had ~50 navigation items across 10 sections for a fleet of 13
   handsets. That is feature-centric navigation: you had to know which of
   fifty tools did the thing you wanted. v63 is device-centric. The fleet is
   the home screen, a handset is a workspace, and everything you can do to a
   phone lives inside that phone's tabs.

   Chrome:  a full-width command bar on top, a narrow rail beneath it, and
            one content column. The bar spans everything so global search
            and fleet state are always in the same place.

   VISUAL LANGUAGE
   Taken from the hardware. A BLF key has four lamp states — dark, green
   idle, amber ringing, red busy — and those four signals are the entire
   palette. Everything else is anodised equipment grey, so the only things
   that glow are the things reporting state.
