 * ```html
 * <!-- Simple usage - show content if customer has feature -->
 * <div *subFeatureGate="'premium_analytics'">
 *   Premium Analytics Dashboard
 * </div>
 *
 * <!-- With else template -->
 * <div *subFeatureGate="'export_data'; else: noAccess">
 *   <button (click)="exportData()">Export Data</button>
 * </div>
 * <ng-template #noAccess>
 *   <button (click)="showUpgradeModal()">Upgrade to Export</button>
 * </ng-template>
 *
 * <!-- With explicit customer ID -->
 * <div *subFeatureGate="'premium_analytics'; customerId: 'cus_123'">
 *   Content
