+/**
+ * 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.
