   INTERACTIVE ARCHITECTURE DIAGRAM
   A fifteen-connection diagram is a thicket until you can isolate
   one line. Hovering (or tabbing to) a connection glows it and
   fades the rest; clicking its number pins a detail card so the
   information lives next to the thing it describes instead of in
   a list below the fold.
