- Add getTotalSlots() method to base-item.mjs as unified interface - Add slotsWhenEquipped field to weapon, armor, and equipment schemas - Implement getTotalSlots() in each item type respecting equipped state - Update actor slot calculation to use getTotalSlots() uniformly - Add _onUpdate hook to sync equipment effects with equipped state - Update backpack with slotsWhenEquipped: 0 and +2 slot bonus effect Backpack now correctly: - Costs 1 slot when unequipped, 0 when equipped - Grants +2 max item slots via Active Effect when equipped 🤖 Generated with [Claude Code](https://claude.com/claude-code) Co-Authored-By: Claude Opus 4.5 <noreply@anthropic.com>
