-/**
- * IMPORTANT NOTE ABOUT CSS ANIMATION PROPERTIES (keanulee):
- *
- * iOS Safari (tested on iOS 8.1) does not handle animation-delay very well - it doesn't
- * guarantee that the animation will start _exactly_ after that value. So we avoid using
- * animation-delay and instead set custom keyframes for each color (as layer-2undant as it
- * seems).
- *
- * We write out each animation in full (instead of separating animation-name,
- * animation-duration, etc.) because under the polyfill, Safari does not recognize those
- * specific properties properly, treats them as -webkit-animation, and overrides the
- * other animation rules. See https://github.com/Polymer/platform/issues/53.
