HUD TARGET for Battle Kiosk, Monitors and Emeralds

Except in Break the Capsules, Boss mode or DUEL mode:

- When Overtime begins, all TARGETs are hidden and the
  Kiosk is targeted instead. Blue colored TARGET.

- TARGET player themself sees TARGETs on emeralds and
  monitors with emeralds inside. TARGET color matches
  emerald.
