Theorem number font and final period with mdframed

Question

I am using mdframed, and I would like the theorem number to have the same font as the theorem name, like it is shown here:

Also, the theorem number should finish with a period: "Example 1.1.", "Example 1.2."

Here is my MWE:

\documentclass{article}

\usepackage{roboto}
\usepackage{fourier}

\usepackage{amsthm, amsmath}

\usepackage[usenames,dvipsnames,table]{xcolor} 
\definecolor{blue-header}{RGB}{130,160,200}

\usepackage[framemethod=latex]{mdframed}

\theoremstyle{ejemplo}
\mdfdefinestyle{estiloejemplo}{%
    topline=false,
    leftline=true,
    bottomline=false,
    rightline=false,
    linewidth = 4pt, %
    linecolor = blue-header,
    frametitleaboveskip = 0,  % distancia del teorema a la parte superior 
    innerrightmargin = 0,     % margen derecha
    frametitlefont = \normalfont,
    innerbottommargin = 0,    % distancia del teorema a la parte inferior
    theoremtitlefont = \itshape,
} 

\mdtheorem[style=estiloejemplo]{ejemplo}{\textbf{\textsf{\textcolor{blue-header}{Example}}}}[section]

\begin{document}
    \section{A section}
    Some text.
    
    \begin{ejemplo}[This is the title of the exercise, which spans several lines and should be in italic font. This is the title of the exercise, which spans several lines and should be in italic font]
    where $m$ is the slope, and $b$ is the intersect.     where $m$ is the slope, and $b$ is the intersect. 
    \end{ejemplo}

    Some other test

    \begin{ejemplo}
        This is another example
    \end{ejemplo}      

The final text
\end{document} 

Answer 1

I solved my own question:

with the following code:

\documentclass{article}

%fonts
\usepackage{roboto}
\usepackage{fourier}

\usepackage{amsthm, amsmath}

\usepackage[usenames,dvipsnames,table]{xcolor} 
\definecolor{blue-header}{RGB}{130,160,200}

\usepackage[framemethod=latex]{mdframed}
    
\newcounter{ejemplo}[section]
\newenvironment{ejemplo}[1][]{%
    \refstepcounter{ejemplo}%
    \ifstrempty{#1}%
    {%
        \mdfsetup{frametitle={\textbf{\textsf{\textcolor{blue-header}{Example~\theejemplo.}}}}}
    }%
    {%
        \mdfsetup{frametitle={\textbf{\textsf{\textcolor{blue-header}{Example~\theejemplo.}}}~\textit{#1}}}
    }%
    \mdfsetup{%
        topline=false,
        leftline=true,
        bottomline=false,
        rightline=false,
        linewidth = 4pt, %
        linecolor = blue-header,
        %    skipabove = 40,          % distancia superior
        %    skipbelow = 40,          % distancia inferior
        frametitleaboveskip = 0,  % distancia del teorema a la parte superior 
        innerrightmargin = 0,     % margen derecha
        frametitlefont = \normalfont,
        innerbottommargin = 0,    % distancia del teorema a la parte inferior
        theoremtitlefont = \itshape,
    } 
    \begin{mdframed}[]\relax%
    }{\end{mdframed}}
    
\renewcommand{\theejemplo}{\thesection.\arabic{ejemplo}}% ...for chapter prefix
    
    
\begin{document}    
    \section{A section}
Some text.

\begin{ejemplo}[This is the title of the exercise, which spans several lines and should be in italic font. This is the title of the exercise, which spans several lines and should be in italic font]

    %    And there is and equation:

        %        f(x) &= mx+b &
        %        I &= \int_a^b f(x) \mathrm{d}\!x
        %    \end{align}
    where $m$ is the slope, and $b$ is the intersect.     where $m$ is the slope, and $b$ is the intersect.
