   Word Unscrambler — design system
   Identity: a card-table world. Deep felt-green surfaces, ivory letter
   tiles with engraved walnut ink and gold point values (borrowed straight
   from the real tile game this tool serves), one scarlet accent doing the
   work of a "triple word score" square, one cobalt accent doing the work
   of a "double letter score" square.
