+/**
+ * Sentry Utilities
+ *
+ * This file provides utility functions for reporting errors to Sentry,
+ * a platform for monitoring and tracking errors in real-time.
+ * These utilities help streamline the process of capturing and
+ * sending error information to Sentry for better debugging and
+ * error management in the application.
+ *
+ * Note: These functions rely on the Sentry configuration of the main application.
+ * The Sentry setup and initialization should be handled in the main application,
+ * not in this submodule. See frontends/app/src/integrations.ts for the Sentry setup.
