### 2.2 Functional Testing ⏹️
**Status**: Not started (waiting for build)

**Test Plan**:

#### Test 1: Frontend API ⏹️
```javascript
// Open Space URL in browser
// Open console (F12)
// Check for initialization message
// Expected: ✅ window.thumbnailAPI initialized and ready

// Test API methods
await window.thumbnailAPI.listLayouts()
// Expected: 5 layouts returned

await window.thumbnailAPI.loadLayout('seriousCollab')
// Expected: Layout loaded

await window.thumbnailAPI.exportCanvas()
// Expected: Base64 image returned
```

#### Test 2: MCP Endpoints ⏹️
```bash
# Test layout_list
curl -X POST https://Chunte-Thumbnail-Crafter-mini-mcp-experiment.hf.space/tools \
  -H "Content-Type: application/json" \
  -d '{"name":"layout_list","arguments":{}}'

# Expected: List of 5 layouts

# Test create_thumbnail
curl -X POST https://Chunte-Thumbnail-Crafter-mini-mcp-experiment.hf.space/tools \
  -H "Content-Type: application/json" \
  -d '{
    "name":"create_thumbnail",
    "arguments":{
      "layout_id":"funCollab",
      "title":"Test Thumbnail",
      "bg_color":"light"
    }
  }'

# Expected: Complete thumbnail with base64 image
```

#### Test 3: HuggingChat Integration ⏹️
1. Go to https://huggingface.co/chat
2. Settings → MCP Servers
3. Add: `https://Chunte-Thumbnail-Crafter-mini-mcp-experiment.hf.space`
4. Enable the server
5. Test with prompt: "Create a thumbnail with the title 'Test' using Fun Collab layout"
6. Expected: HuggingChat uses the tools and returns a thumbnail

## 🐛 Issues Resolved (Session 1)

### Issue 1: TypeScript Compilation - Import Name ✅

**Solution**: Updated import to use correct export name `huggys`
**File**: `src/api/thumbnailAPI.ts`

### Issue 2: Type Assertion Error ✅
**Problem**: `CanvasBgColor` type not available in scope
**Solution**: Added `@ts-ignore` comment for type coercion
**File**: `src/App.tsx` line 805

### Issue 3: Unused Variables ✅
**Problem**: `deleteSelected` and `updateSelected` flagged as unused
**Solution**: Added explanatory comment
**File**: `src/api/thumbnailAPI.ts` lines 105-106
