🧪 Usage

package main

    logger.LogSuccess("Servidor iniciado correctamente")
    logger.LogInfo("Escuchando en el puerto %d", 8080)
    logger.LogWarn("Límite de peticiones alcanzado para el cliente %s", "client_123")
    logger.LogError("Error al conectar con la base de datos: %s", "timeout")
    logger.LogFatal("Error crítico: %s", "token inválido")
}
