+/// Daemon process for background analysis and service management.
+///
+/// The `daemon` module provides functionality for running the photoacoustic analysis
+/// system as a background service. It is responsible for orchestrating continuous data
+/// acquisition, periodic analysis, and automatic reporting, as well as managing the
+/// lifecycle of long-running server or worker processes.
+///
+/// Key features of the daemon module include:
+/// - Background monitoring and scheduling of analysis tasks
+/// - Integration with system process management (e.g., for Unix daemons or Windows services)
+/// - Graceful startup and shutdown handling
+/// - Logging, diagnostics, and error recovery mechanisms
+/// - Secure management of credentials and configuration for unattended operation
+///
+/// This module is intended for scenarios where the photoacoustic system must operate
+/// autonomously, such as in industrial monitoring, environmental sensing stations, or
+/// deployments requiring persistent, headless operation.
