/* One palette, and it is the app's. static/css/style.css has been dark since
 * the first commit, and these two pages -- which exist to show that app --
 * were light, so the demo looked like a different product from the thing it
 * demonstrates. The hues below are style.css's, re-expressed as the roles
 * this stylesheet uses. A visitor who genuinely wants light can set
 * data-theme="light"; nothing else switches it, because following the
 * operating system would mean the screenshots in the README match for some
