  • Secondary: CombatDataTransfer session data
  • Fallback: String-based inventory descriptions
• Enhanced item display with quantity support (e.g., "Health Potion x3")
• Added usability checks - items with 0 quantity are disabled
• Improved error handling and debug logging

3. EnhancedBattleTestMode.cs Inventory Creation
