-- Automated tests for Game3 Pokemon Summary Screen
-- Validates:
-- 1. Chrome asset loading from data/generated/gba (game3 launcher scope)
-- 2. Anti-PP swap trap protection (atomic swapMoves)
-- 3. Dynamic trade memo detection (OT Name / ID / SID diff against PlayerState)
-- 4. Page transitions (INFO -> SKILLS -> MOVES -> MOVE_DETAIL)
-- 5. Modal Stack integration with PartyMenu
