+ * No-op Analytics Service Implementation.
+ *
+ * This service implements the AnalyticsService interface but does nothing.
+ * It's used as a fallback when analytics are disabled or not configured.
+ *
+ * @example
+ * ```typescript
+ * // Service creation (usually done by create-services.ts)
+ * const service = new NoopAnalyticsService();
+ *
+ * // These calls do nothing but are safe to execute
+ * service.track('button_click', { button_id: 'cta' });
+ * service.trackPageview('/products/123');
+ * ```
+ *
+ * @example
+ * ```typescript
+ * // Automatic fallback in create-services.ts
+ * const umamiEnabled = Boolean(process.env.NEXT_PUBLIC_UMAMI_WEBSITE_ID);
+ * const analytics = umamiEnabled
+ *   ? new UmamiAnalyticsService({ enabled: true })
+ *   : new NoopAnalyticsService(); // Fallback when no website ID
+ * ```
