文本、\backgroundcolor 和 \tikz 之间的重叠顺序

Question

我有以下文档布局，由两列文本（这里只有左列有一些文本）、文档左列上的灰色背景条纹和整个页面边框处的黄色框架组成：

\documentclass[a4paper]{article}
\usepackage[a4paper,
        left   = 0.2cm,
        right  = 0.2cm,
        top    = 0.1cm,
        bottom = 0.2cm]{geometry}
\usepackage{paracol}
\usepackage{xcolor}
\usepackage{lipsum}
\usepackage{tikz}

\backgroundcolor{c[0](5pt,3pt)(0.5\columnsep,3pt)}[rgb]{0.95,0.95,0.95}

\begin{document}

% Yellow frame
% https://tex.stackexchange.com/questions/452538/how-to-insert-a-frame-for-a-page-in-latex
\tikz[overlay, remember picture] \draw[draw=yellow,line width=0.7cm] ([xshift=0cm,yshift=-0cm]current page.north west) rectangle ([xshift=-0cm,yshift=0cm]current page.south east);

% 2-column text
\columnratio{0.4}
\begin{paracol}{2}
\lipsum[1-3]
% \switchcolumn 
\lipsum[2-6]
\end{paracol}

但我想将文本作为第一层/顶层，黄色框作为第二层/中间层，灰色背景作为第三层/底层，如下图所示（使用 power point 制作）：

如何按照描述的顺序使这三个层之间实现重叠？

Answer 1

我的尝试……

\documentclass[a4paper]{article}
\usepackage[a4paper,
        left=0.2cm,
        right=0.2cm,
        top=0.1cm,
        bottom=0.2cm]{geometry}
\usepackage{paracol}
\usepackage{xcolor}
\usepackage{lipsum}
\usepackage{tikz}


\begin{document}


% Yellow frame first on  bottom layer
\begin{tikzpicture}[remember picture,overlay]
    \draw[draw=yellow,line width=0.7cm] ([xshift=0cm,yshift=-0cm]current page.north west) rectangle ([xshift=-0cm,yshift=0cm]current page.south east);
\end{tikzpicture}

% Gray background in second layer <= Adjust the dimensions and position to fit your layout
\begin{tikzpicture}[remember picture,overlay]
    \fill[gray!30] (0.2cm,-0.1cm) rectangle (\textwidth-0.4cm,-\textheight+0.3cm); % Adjust these dimensions
\end{tikzpicture}

% your text content finally so it appears on top
\columnratio{0.4}
\begin{paracol}{2}
    \lipsum[1-3]
    \lipsum[2-6]
\end{paracol}

\end{document}

已编辑：@samcarter_is_at_topanswers.xyz 在后续问题中接受的答案“tikzpicture 移动文本“，这就是我所寻找的。也非常感谢@JeT 的第一次出色提示和尝试！

谢谢@JeT，很接近...黄色框架与灰色背景切换了..

\documentclass[a4paper]{article}
\usepackage[a4paper,
        left=0.2cm,
        right=0.2cm,
        top=0.1cm,
        bottom=0.2cm]{geometry}
\usepackage{paracol}
\usepackage{xcolor}
\usepackage{lipsum}
\usepackage{tikz}


\begin{document}

% Gray background at the bottom
\begin{tikzpicture}[remember picture,overlay]
    \fill[gray!30] ([xshift=0cm,yshift=-0cm]current page.north west) rectangle  ([xshift=-12.5cm,yshift=0cm]current page.south east); % Adjust these dimensions
\end{tikzpicture}

% Yellow frame as a second layer
\begin{tikzpicture}[remember picture,overlay]
    \draw[draw=yellow,line width=0.7cm] ([xshift=0cm,yshift=-0cm]current page.north west) rectangle ([xshift=-0cm,yshift=0cm]current page.south east);
\end{tikzpicture}

% Text on top
\columnratio{0.4}
\begin{paracol}{2}
    \noindent\lipsum[1-3]
    \noindent\lipsum[2-6]
\end{paracol}

\end{document}

但是，仍然存在如何使 lipsum 的文本从左上角开始的问题...事实上，它看起来像是将tikzpicture文本向下移动...

（我尝试了几次，但无法解决这个问题 - 因此我打开了一个新问题）
