/* Parable of the Polygons, by Vi Hart and Nicky Case (2014), played from its
 * own files in polygons/ (js/playables.js in the engine runs the frames).
 *
 * These slides keep the post's look: its light grey page (#eee), which its
 * pictures (the "drag & drop" arrow) are drawn on, with its bigger
 * simulations and its header on dark bands (#222). They stay light in dark
 * mode, since the post's pictures can't change colour. The words are the
 * post's own. They're set in Nunito Sans, the decks' stand-in for Gill Sans,
 * because the post is full of numbers (50%, 1/3, 1971) and in Gill Sans a 1
 * reads as a capital I.
 *
 * The talk (talk/index.html) shows the same slides and uses this sheet too.
