   sunoku.app — site.css

   Phone first: everything below is the 375px layout, and the media
   queries at the end of each section widen it. The colours are the
   game's own tokens (css/styles.css in the game), so the board, the hint
   bar and the buttons in board.css look exactly as they do in the app.
   One theme: the game's dark one, which is what the screenshots show.
