   Jazz Guitar Triad Pair Finder — triadpairs.css
   Loaded after analyzer.css.

   One distinction carries this whole tool: which of the two triads a
   note belongs to. It is drawn twice over — a colour AND a shape, circle
   against square — because a legend that depends on colour alone fails
   on a greyscale printer and on a colour-blind reader, and this is the
   one thing the diagram cannot afford to be vague about.
