/* ============================================================================
   University of Michigan Athletics — SLDP preroll player
   Page identity + the "pill" control treatment.

   The player has three visual states, each of which fully replaces the
   contents of #player-container:

     1. Click-to-play   → .click-to-play-overlay        (index.html)
     2. Preroll ad      → .preroll-ad-wrapper            (preroll-manager.js)
     3. Live stream     → #sldp-player + SLDP internals  (sldp-*.min.js)

   All three render as the same rounded pill (see PILL CHROME below) so the
   handoff between states reads as one continuous control, not three UIs.
   Ad-specific rules live in css/preroll.css.

   Colors are the primary Michigan Athletics palette only (Brand Guide 08.2020):
     Maize #FFCB05 · Blue #00274C · White
   Accessible pairings used here, per the guide: maize-on-blue, white-on-blue,
   blue-on-maize. (White-on-maize is NOT an approved combination.)

   STATE 3 — LIVE STREAM (SLDP control bar)
   The SLDP library injects its own DOM into #sldp-player. The rules below
   are ported from a proven production override of the same player:
     · the control bar ships ~30px tall with hidden overflow, which slices a
       44px round button into an ellipse — unclip every ancestor
     · the player sets inline zoom:2 on mobile — undo it
     · the play/pause glyph is drawn by the player via ::before — keep it
       centered by forcing transform off; we only color and frame it
