/* ============================================================================
   University of Michigan Athletics — preroll ad state
   Loads after css/player.css and inherits its custom properties.

   Audio creative (the usual case for this player):
     .preroll-ad-wrapper.preroll-audio-mode renders as the same pill as the
     other states — pulse dot, "Advertisement", then Learn More / Skip on the
     right. The pill chrome itself is defined once in player.css.

   Video creative (possible when a tag offers no audio media file):
     the wrapper leaves the pill and becomes a rounded 16:9 panel with the
     badge and buttons in its corners.
