## Task Description
Fix LootTab nesting (remove redundant layers) (PRIORITY 3b)

## Source Files

### 1. `/src/components/game/tabs/LootTab.tsx` (48 lines)

**Full Content:**
```typescript
'use client';

import { Card, CardContent, CardHeader, CardTitle } from '@/components/ui/card';
import { Badge } from '@/components/ui/badge';
import type { GameStore } from '@/lib/game/store';
import { LootInventoryDisplay } from '@/components/game/LootInventory';

export interface LootTabProps {
  store: GameStore;
}

export function LootTab({ store }: LootTabProps) {
  const inventory = store.lootInventory;
  const elements = store.elements;
  const equipmentInstances = store.equipmentInstances;
  
  // Count items for badge
  const materialCount = Object.values(inventory.materials).reduce((a, b) => a + b, 0);
  const blueprintCount = inventory.blueprints.length;
  const equipmentCount = Object.keys(equipmentInstances).length;
  const totalItems = materialCount + blueprintCount + equipmentCount;
  
  return (
    <div className="space-y-4">
      <Card className="bg-gray-900/80 border-gray-700">
        <CardHeader className="pb-2">
          <CardTitle className="text-amber-400 text-sm flex items-center gap-2">
            💎 Loot Inventory
            <Badge className="ml-auto bg-gray-800 text-gray-300">
              {totalItems} items
            </Badge>
          </CardTitle>
        </CardHeader>
        <CardContent>
          <LootInventoryDisplay
            inventory={inventory}
            elements={elements}
            equipmentInstances={equipmentInstances}
            onDeleteMaterial={store.deleteMaterial}
            onDeleteEquipment={store.deleteEquipmentInstance}
          />
        </CardContent>
      </Card>
    </div>
  );
}

LootTab.displayName = "LootTab";
```

**Key Observations - LootTab Redundant Wrapper:**
- Uses `Card` component from `@/components/ui/card` with header "💎 Loot Inventory"
- Shows a badge with total items count
- Wraps `LootInventoryDisplay` inside `CardContent`
- **This creates the outer layer of nesting**

### 2. `/src/components/game/LootInventory.tsx` (499 lines)

**Component Interface:**
```typescript
interface LootInventoryProps {
  inventory: LootInventoryType;
  elements?: Record<string, ElementState>;
  equipmentInstances?: Record<string, EquipmentInstance>;
  onDeleteMaterial?: (materialId: string, amount: number) => void;
  onDeleteEquipment?: (instanceId: string) => void;
}
```

**Main Component Export:**
```typescript
export function LootInventoryDisplay({ 
  inventory, 
  elements,
  equipmentInstances = {},
  onDeleteMaterial,
  onDeleteEquipment,
}: LootInventoryProps) {
  // ... state and handlers ...
  
  // Check if we have anything to show
  const hasItems = totalItems > 0 || essenceCount > 0;

  if (!hasItems) {
    return (
      <GameCard variant="default" className="w-full">
        <div className="flex items-center gap-2 mb-2">
          <Gem className="w-4 h-4 text-[var(--mana-light)]" />
          <h3 className="text-[var(--mana-light)] game-panel-title text-xs uppercase tracking-wider">
            Inventory
          </h3>
        </div>
        <div className="text-[var(--text-muted)] text-sm text-center py-4">
          No items collected yet. Defeat floors and guardians to find loot!
        </div>
      </GameCard>
    );
  }
  
  // ... handlers ...
  
  return (
    <>
      <GameCard variant="default" className="w-full">
        <div className="flex items-center gap-2 mb-3">
          <Gem className="w-4 h-4 text-[var(--mana-light)]" />
          <h3 className="text-[var(--mana-light)] game-panel-title text-xs uppercase tracking-wider">
            Inventory
          </h3>
          <Badge 
            className="ml-auto bg-[var(--bg-sunken)] text-[var(--text-secondary)] text-xs border-[var(--border-subtle)]"
            aria-label={`${totalItems} items in inventory`}
          >
            {totalItems} items
          </Badge>
        </div>
        
        {/* Search and Filter Controls */}
        {/* ... */}
        
        {/* Filter Tabs */}
        {/* ... */}
        
        <Separator className="bg-[var(--border-subtle)] mb-3" />
        
        <ScrollArea className="h-64 w-full">
          {/* Materials, Essence, Blueprints, Equipment sections */}
          {/* ... */}
        </ScrollArea>
      </GameCard>
      
      {/* Delete Confirmation Dialog */}
      <AlertDialog open={!!deleteConfirm} onOpenChange={() => setDeleteConfirm(null)}>
        {/* ... */}
      </AlertDialog>
    </>
  );
}
```

**Key Observations - LootInventory Redundant Wrapper:**
- Uses `GameCard` component (from `@/components/ui/game-card`)
- Has its own header with "Inventory" title and `Gem` icon
- Shows a badge with total items count (duplicating LootTab's badge)
- Contains all the actual content: search, filters, items display
- **This creates the inner layer of nesting**

---

## 3. Duplicate Headings/Wrappers Issue

### Redundant Card Nesting:
```
LootTab (Outer Card)
├── CardHeader: "💎 Loot Inventory" + Badge: "{totalItems} items"
└── CardContent
    └── LootInventoryDisplay (Inner GameCard)
        ├── Header: "Inventory" + Badge: "{totalItems} items"  ← DUPLICATE
        ├── Search/Filter Controls
        ├── Items Display
        └── Delete Dialog
```

### Specific Code Duplication:

**LootTab.tsx (lines 24-33) - Outer Header:**
```tsx
<CardHeader className="pb-2">
  <CardTitle className="text-amber-400 text-sm flex items-center gap-2">
    💎 Loot Inventory
    <Badge className="ml-auto bg-gray-800 text-gray-300">
      {totalItems} items
    </Badge>
  </CardTitle>
</CardHeader>
```

**LootInventory.tsx (lines 191-202) - Inner Header (DUPLICATE):**
```tsx
<div className="flex items-center gap-2 mb-3">
  <Gem className="w-4 h-4 text-[var(--mana-light)]" />
  <h3 className="text-[var(--mana-light)] game-panel-title text-xs uppercase tracking-wider">
    Inventory
  </h3>
  <Badge 
    className="ml-auto bg-[var(--bg-sunken)] text-[var(--text-secondary)] text-xs border-[var(--border-subtle)]"
    aria-label={`${totalItems} items in inventory`}
  >
    {totalItems} items
  </Badge>
</div>
```

### Redundant Badge Count:
- LootTab shows: `{totalItems} items` 
- LootInventoryDisplay also shows: `{totalItems} items`
- Both calculate the same `totalItems` value

## 5. Comparison with Other Tabs

Looking at other tabs in `/src/components/game/tabs/`:

- **EquipmentTab.tsx**: Uses `GameCard` directly without an outer `Card` wrapper
- **CraftingTab.tsx**: Uses multiple `GameCard` components for different sections, no outer `Card`
- **GolemancyTab.tsx**: Uses `GameCard` directly
- **LabTab.tsx**: Uses `GameCard` directly

**Pattern**: Most tabs render their content directly using `GameCard` components without an additional `Card` wrapper from the tab itself.

---

## 6. Summary of Issues to Fix

1. **Redundant Card Wrapper in LootTab**: The `Card` + `CardHeader` + `CardContent` wrapper in LootTab.tsx is unnecessary since LootInventoryDisplay already provides its own `GameCard` wrapper.

2. **Duplicate Header**: Both LootTab and LootInventoryDisplay show similar headers with:
   - Title text ("Loot Inventory" vs "Inventory")
   - Item count badge
   - Icon (emoji 💎 vs Gem icon)

3. **Double Wrapping**: Content is wrapped in two card-like components:
   - Outer: `Card` from `@/components/ui/card`
   - Inner: `GameCard` from `@/components/ui/game-card`

4. **Solution Direction**: Remove the outer `Card` wrapper from LootTab.tsx and let LootInventoryDisplay handle the card styling, OR remove the inner `GameCard` from LootInventoryDisplay and keep only the outer wrapper.

---

## 7. Files That Would Need Modification

1. **`/src/components/game/tabs/LootTab.tsx`** - Remove outer Card wrapper, pass props directly to LootInventoryDisplay
2. **`/src/components/game/LootInventory.tsx`** - Potentially remove GameCard wrapper if keeping LootTab's Card, or keep as-is if removing LootTab's Card

**Recommended Approach**: Remove the outer `Card` wrapper from `LootTab.tsx` and let `LootInventoryDisplay` handle the full display (since it already has a complete GameCard wrapper with header, controls, and content).
