在 LaTeX 中复制带边框的文本样式

Question

我希望使用 LaTeX 复制以下艺术品：

左侧有一条类似铅笔的边框。铅笔被分成不同颜色的部分，对应不同的信息。每段文本还被赋予不同长度的“参考”（副标题）。围绕每个副标题的彩色圆角矩形标签的长度也应有所不同，以适合整个副标题。

如何用 tikz 实现这一点？

以下由 Marco Daniel 编写的代码可作为起点，并实现类似（但大大简化）的效果，即仅沿某段文本的左侧绘制一条线。

\documentclass[a4paper,10pt]{article}
\usepackage[utf8]{inputenc}
\usepackage[x11names, svgnames]{xcolor}
\usepackage[framemethod=tikz]{mdframed}
\usetikzlibrary{calc}
\usepackage{fourier-orns}
\definecolor{warningColor}{named}{Red3}
\tikzset{
  warningsymbol/.style={
      rectangle,
      draw=warningColor,
      fill=white,
      scale=1,
      overlay}
}

\mdfdefinestyle{warning}{%

                           node[warningsymbol] {\danger};},%
}

\newmdenv[style=warning]{Warning}

\usepackage{lipsum}


\begin{document}
\begin{Warning}
    \lipsum[1]
\end{Warning}
\lipsum[1]

\begin{Warning}
    \lipsum\lipsum[1]
