/* ============================================================================
   test-play-game.css — "Arcade" theme for the Python Test play screen.
   Re-skinned to the brand identity (violet #7c3aed / cyan #0ea5e9) to match the
   Tests catalogue. Green is reserved for "correct/passed" and coral for
   "wrong/lost" semantics only. Gold is the arcade "you are here" beacon + heat.
   Question surfaces stay light for legibility; chrome goes dark violet.
