/* KohAI site. White and near white, with the app's blue and green (app/renderer/theme.css) as the two
   brand colors. Bold type, hard pixel shadows and pixel art that matches Brackets. Light only: the brand is white.

   reduced motion), so with reduced motion the page is complete and still. There is no pause button. */
