## 🔧 Technical Details

### Real-Time Polling Implementation

```javascript
// Main polling loop
async function updateAllData() {
    await Promise.all([
        updateStats(),              // Always update
        updatePropertiesIfNeeded(),  // If visible
        updateLeadsIfNeeded(),       // If visible
        updateVisitsIfNeeded(),      // If visible
        updateDocumentsIfNeeded()    // If visible
    ]);
}

// Start polling
startPolling() // Runs every 5 seconds
```

### Smart Tab Detection

```javascript
// Only update if tab is visible
async function updateLeadsIfNeeded() {
    const visibleTab = document.querySelector(
        '.tab-content:not([style*="display: none"])'
    );
    if (visibleTab?.id !== 'leads') return; // Skip if not visible
    
    // Fetch and render leads
}
```

### Real-Time Status Updates

```javascript
// Instantly update UI
async function submitLeadResponse(e) {
    e.preventDefault();
    
    // Send to API
    const response = await fetch('api/broker/manage-lead.php', {
        method: 'POST',
        body: JSON.stringify({
            inquiry_id: id,
            action: 'respond',
            response: message
        })
    });
    
    // Show notification
    showNotification('Response sent! ✅', 'success');
    
    // Refresh data
    await updateLeadsIfNeeded();
}
```

## 🐛 Error Handling

// Catches network failures
try {
    const response = await fetch(API_BASE + 'get-stats.php');
    const data = await response.json();
} catch (error) {
    console.error('Error updating stats:', error);
    // Shows error notification to user
}
```

### API Errors
```javascript
if (!data.success) {
    showNotification(
        data.message || 'An error occurred',
        'error'
    );
}
```

### Session Timeouts
```javascript
if (!response.ok) {
    // Redirect to login if session expired
    window.location.href = '../broker-login.php';
}
```
