/**
 * Structural directive for gating content based on NUMERIC entitlement quotas
 *
 * This directive shows or hides content based on whether the current usage is
 * within the customer's quota limit. It's useful for enforcing usage limits
 * on actions like creating projects, uploading files, etc.
 *
 * @example
 * ```html
 * <!-- Simple usage - show if within limit -->
 * <button *subQuotaGuard="'max_projects'; current: projectCount"
 *         (click)="createProject()">
 *   Create New Project
 * </button>
 *
 * <!-- With else template -->
 * <button *subQuotaGuard="'max_projects'; current: projectCount; else: limitReached"
 *         (click)="createProject()">
 *   Create Project
 * </button>
 * <ng-template #limitReached>
 *   <div class="warning">
 *     <p>Project limit reached ({{ projectCount }}/{{ limit }})</p>
 *     <button (click)="showUpgradeModal()">Upgrade Plan</button>
 *   </div>
 * </ng-template>
 *
 * <!-- With explicit customer ID -->
 * <button *subQuotaGuard="'max_storage_gb'; current: usedStorage; customerId: 'cus_123'"
 *         (click)="uploadFile()">
 *   Upload File
 * </button>
 * ```
