```javascript
app.use(async (req, res, next) => {
    const validation = await SecureGuard.validateLicense();
    if (!validation.isValid) {

    }
    next();
});
```

### 3. Component Usage ✅
```javascript
// Individual components work independently
const OfflineManager = require('@ufdevsllc/auth-me/OfflineManager');
const FallbackManager = require('@ufdevsllc/auth-me/FallbackManager');

const offlineManager = new OfflineManager();
await offlineManager.initialize();
```
