-- Driver: #194 Celadon prize room must require the COIN CASE.
-- engine/menus/prize_menu.asm CeladonPrizeMenu gates the prize window on the
-- COIN CASE: IsItemInBag COIN_CASE first, and with no case it prints
-- RequireCoinCaseText and returns without ever opening a window; only with the
-- case does it print ExchangeCoinsForPrizesText and then show the prize list.
-- The port used to open "PRIZES (COINS)" unconditionally with no intro line.
--
-- The three prize counters are bg-event signs at cells (2,2),(4,2),(6,2) in
-- GAME_CORNER_PRIZE_ROOM (data/generated/maps.lua).  Stand south of vendor 1
-- and press A: no-case -> require box and NO list; has-case -> exchange box,
-- then the prize list; cancel returns to the overworld (onCancel == done).
