使用 tikz 和 framed 将“连续”文本添加到框架段落

Question

我尝试改编以下示例： http://www.texample.net/tikz/examples/framed-tikz/

到目前为止，我已经成功更改了配色方案，并用简单的圆角边框替换了不规则的边缘。我想要实现的最后一个更改是让框的标题在框继续进入下一页时再次出现，并带有后缀“继续”。

该示例根据框的位置应用了不同的样式，并希望对标题使用相同的方法，但我在将标题添加到宏时遇到了困难。以下是我目前所拥有的：

我建议不要framed使用tcolorbox或者mdframed制作框架和易碎的盒子。您的示例tcolorbox可以适应以下情况：

\documentclass[a5paper]{article}
\usepackage{lipsum}   % To generate test text 
\usepackage[breakable,skins]{tcolorbox}

% Define Colour Styles
\definecolor{Border}{HTML}{204C82}
\definecolor{Background}{HTML}{D2DBE6}

\newtcolorbox{parchment}[2][]{%
    breakable,
    enhanced,
    colback=Background,
    colframe=Border,
    top=4mm,
    enlarge top by=\baselineskip/2+1mm,
    pad at break=\baselineskip,
    fontupper=\normalsize,
    overlay unbroken and first={%
        \node[rectangle, rounded corners, 
              draw=Border, fill=Background,
             inner sep=1mm, anchor=west, font=\small]
       at ([xshift=4.5mm]frame.north west) {\strut\textbf{#2}};},
    overlay middle and last={%
       \node[rectangle, rounded corners, 
             draw=Border, fill=Background,
             inner sep=1mm, anchor=west, font=\small]
       at ([xshift=4.5mm]frame.north west)
          {\strut\textbf{Continue from previous page}};},
#1}%

\begin{document}
\begin{parchment}{Short text}
  \lipsum[11]
\end{parchment}
\lipsum[11]
\begin{parchment}{Long text spanning over pages}
\lipsum[11]
  \begin{itemize}
    \item \lipsum[14]
  \end{itemize}
\lipsum
\end{parchment}
\end{document}
