3. **Expected:** Modal shows "Templates" title
4. **Expected:** Filter buttons: All, Business, Portfolio, Personal
5. **Expected:** Template grid displays with cards

2. Each template card shows:
   - Thumbnail image
   - Template name
   - Description
   - Tags
   - Color dots
3. Hover effect: card should lift and show blue border

#### Filter Templates

#### Close Modal - Multiple Ways
Test all these methods:

2. Press ESC key → modal closes
3. Click dark area outside modal → modal closes

### 4. Error Handling Test

#### Test template loading errors
1. Open browser console (F12)
2. Check for console logs when opening templates
3. Should see: "Loading template index from templates/index.json..."
4. Should see: "Loaded 8 templates"

#### Simulate error (optional)
1. Temporarily rename `templates/index.json` to `index.json.bak`
2. Reload page
3. Open Templates modal
4. Should see friendly error message in grid
5. Console should show detailed error
6. Restore file: rename back to `index.json`

### 5. Integration Test

Full workflow:

2. Click Templates button
3. Filter to "Business"
4. Select "SaaS Landing Page"
5. Confirm in modal
6. Verify template loads correctly
7. Edit template elements (text, colors, etc.)
