# Sub-Task 4: EquipmentTab 2H Offhand Disable (Bug 6)

## Scope
- **Components affected**:
  - `components/EquipmentTab.tsx` (offhand slot logic)
  - Equipment slot rendering components (e.g., `EquipmentSlot.tsx`)
  - Item type checking logic (to detect 2-handed weapons)
- **Files potentially affected**:
  - `types/items.ts` (item type definitions for 2-handed weapons)
  - `store/equipmentSlice.ts` or similar state management for equipment
  - `utils/itemUtils.ts` for item type helper functions

## Acceptance Criteria
1. When a 2-handed staff (or any 2-handed weapon) is equipped in mainhand, offhand slot is visibly disabled/occupied (verify visually: grayed out, tooltip indicating why)
2. Player cannot equip any item in offhand while 2-handed weapon is equipped (verify via UI and state checks)
3. Equipping a 2-handed weapon automatically clears any existing offhand item (if required by game logic)

## Dependencies
- None (independent sub-task)

## Estimated Complexity
- Medium (item type logic + UI state management)
