/* ============================================================
   CLASSROOM SHOWDOWN (v2.73.0) — THE GAME SCREEN.

   Left: the indigo side panel — logo, leaderboard, powers, utilities.
   Right: the scenic stage — the team banner, the round pill, the question
   card, the buzzer on its rock, the status pill, and the cheering mascots.

   The buzzer is the Asset Pack's button: the idle art, and the pressed art
   swapped in while the finger is down or the team is already in. Transform
   and opacity only — no layout thrash while thirty kids hammer it.
