Simulations no longer color-code correct/incorrect choices, retry a
failed per-question autosave, or show the RZ coin/ELO badge - users
move on immediately after submitting a timed block, same as a real
exam. The slot machine panel now shows only the cabinet/reels/lever
and a status line (title, banner, controls row, rewards list, and
footer removed), the reels fill the cabinet window instead of
floating in a black border, the coin-burst animation no longer
starts oversized, and the toolbar button is UAT-only via
Brand.is_uat_environment().
