   the layout, panels are drawn with a 1px border, hierarchy comes from type
   size and thin rules. Open Sans throughout.

     blue   #5ea1ff  links
     green  #5eff6c  ".ing", online, added
     yellow #f1ff5e  updated, warnings
     red    #ff6e5e  removed, offline
     orange #ffbd5e  JavaScript language dot
   The primary button is near-white, not coloured.
