- ✅ Compiled CSS included in build

### Dark Mode ✅
- ✅ `prefers-color-scheme: dark` media query
- ✅ WordPress admin color schemes (midnight, ectoplasm)

## Usage Examples

### Basic Badge
```javascript

    text: 'Translated',
    variant: 'success'
});
document.getElementById('container').appendChild(badge.getElement());
```

### With All Features
```javascript
const badge = new Badge({
    text: 'Processing',
    variant: 'warning',
    size: 'large',
    dot: true,
    icon: 'dashicons-clock',

    variant: 'primary',
    pill: true,
    removable: true,
    onRemove: (badge) => {
        console.log('Removed:', badge.options.text);
        badge.destroy();
    }
});
```

### Status Helper
```javascript
const badge = Badge.fromStatus('translated', {
    size: 'large',
    pill: true
});
```

---

## Common Use Cases

### 1. Translation Status Indicators
```javascript
const statuses = ['translated', 'pending', 'failed', 'needs_update'];
statuses.forEach(status => {
    const badge = Badge.fromStatus(status);
    container.appendChild(badge.getElement());
});
```

### 2. Language Tags
```javascript
['English', 'Spanish', 'French'].forEach(lang => {
    const badge = new Badge({
        text: lang,
        variant: 'primary',
        pill: true,
        removable: true,
        onRemove: (b) => b.destroy()
    });
    container.appendChild(badge.getElement());
});
```

### 3. Count Badges
```javascript
const badge = new Badge({
    text: '42',
    variant: 'primary',
    pill: true,
    size: 'small'
});
```

### 4. Feature Flags
```javascript
[
    { text: 'New', variant: 'success' },
    { text: 'Beta', variant: 'warning' },
    { text: 'Deprecated', variant: 'danger' }
].forEach(feature => {
    const badge = new Badge({ ...feature, size: 'small', pill: true });
    container.appendChild(badge.getElement());
});
```

## Build Process

### Build Command
```bash
cd /home/user/Projects/Press.zone/wordpress/wp-content/plugins/multilingual-press-zone/admin
npm run build
```

### Output Files
- `dist/js/main.js` - Compiled JavaScript (includes Badge component)
- Styles are inlined in the JS bundle via webpack

### Development Mode
```bash
npm run dev    # Watch mode for development
npm run watch  # Alternative watch command
```

---

## Testing

### Demo File
Open `admin/demo-badge.html` in a browser to see:
- All variants displayed
- All sizes demonstrated
- Icon integration
- Pill style variations
- Dot indicators
- Removable badges with event logging
- Tooltip functionality
- Status helper presets
- Combined features
- Interactive controls
- Common use cases

### Manual Testing Checklist
- ✅ All 6 variants render correctly
- ✅ All 3 sizes render correctly
- ✅ Icons display properly (requires Dashicons)
- ✅ Pill style applies full rounding
- ✅ Dot indicators show colored dots
- ✅ Remove button appears and functions
- ✅ `onRemove` callback fires correctly
- ✅ Tooltips appear on hover
- ✅ Dark mode colors are readable
- ✅ Keyboard navigation works
- ✅ Focus indicators are visible
- ✅ `destroy()` cleans up properly

---

## Browser Compatibility

- ✅ Chrome/Edge: Last 2 versions
- ✅ Firefox: Last 2 versions
- ✅ Safari: Last 2 versions
- ✅ Modern browsers with ES6 support

---

## Performance

- **Lightweight**: Minimal DOM structure (single `<span>` with optional children)
- **Efficient**: Event listeners cleaned up properly
- **Fast**: CSS transitions for smooth animations
- **No dependencies**: Pure vanilla JavaScript

---

## Backwards Compatibility

### Migration from Old API
The `error` variant is automatically mapped to `danger`:

```javascript
// Old code (still works)
new Badge({ variant: 'error' });

// Automatically converted to
new Badge({ variant: 'danger' });
```

No breaking changes for existing code.

---

## Future Enhancements (Not in Scope)

Potential future additions:
- Badge groups with automatic spacing
- Badge animation presets
- Click handlers (not just remove)
- Custom color variants via CSS variables
- Gradient backgrounds
- Pulsing animations for live status
