	// Before using the logger macros, you may want to configure logging options such as log levels and output streams.
	// By default, the logger outputs to std::cout, but you can add more streams (e.g., files) or set the log level as needed.

	//  - OFF

	// In most cases, you won't need to use CORE logging in game/application code,
	// but it's available for engine-level diagnostics if necessary
	CORE_LOG_TRACE("Initializing {} with age {}", module, age); // Logs a trace-level message, useful for very detailed information
	CORE_LOG_DEBUG("This is an example of a debug message");    // Logs a debug message, typically used for debugging purposes
	CORE_LOG_WARN("This is an example of a warn message");      // Logs a warning, indicating a non-critical issue that should be investigated
	CORE_LOG_ERROR("This is an example of an error message");   // Logs an error, signaling that something has gone wrong but the engine can still run
	CORE_LOG_CRITICAL("This is an example of a critical message"); // Logs a critical issue, often indicating a major problem in the core system that needs immediate attention.
	// CORE_LOG_FATAL: Logs a fatal error that crashes the application. Fatal errors in the core usually lead to dumping information into crash logs
	// and stopping the program. Use with extreme caution and only in situations where the application can't recover
	// CORE_LOG_FATAL("This is an example of a fatal message");

	LOG_TRACE("App took longer to respond than expected: {} seconds", 2.34); // Logs a trace message, ideal for fine-grained, verbose debugging details
	LOG_DEBUG("This is an example of a debug message");   // Logs a debug message, typically used to help trace the execution during development
	LOG_WARN("This is an example of a warn message");     // Logs a warning, indicating something unexpected happened, but the application can continue running
	LOG_ERROR("This is an example of an error message");  // Logs an error, signaling that an issue occurred that may require attention but is not catastrophic
	LOG_CRITICAL("This is an example of a critical message"); // Logs a critical message, suggesting something very wrong happened, but the program may still attempt to run

	// LOG_FATAL: Logs a fatal error in the application layer. This will trigger the Fatal Handler, which you can override
	// The Fatal Handler provides a mechanism for handling unrecoverable errors gracefully, allowing you to define how the application reacts to fatal crashes
	// LOG_FATAL("This is an example of log fatal crash!");
