I want to print a red page border on the very edge of the pages of my document.
1. Is there any way to achieve it without using `tikz` and `remember picture,overlay`? E.g. `picture` environment or even with `hrule` and `vrule`?
2. I just tried to do it with tikz, but I don't know why the anchors are not set correctly: The red circle is not in the page center and the rectangle (the page border) is not placed on the page corners. MWE:
```
% !TEX TS-program = lualatex
\begin{filecontents}{myclass.cls}
\NeedsTeXFormat{LaTeX2e}
\ProvidesClass{myclass}[2024/09/13 My document class]
\renewcommand\normalsize{\fontsize{18pt}{22pt}\selectfont}
\end{filecontents}
\documentclass{myclass}
\synctex=0
\pageheight 13cm \pagewidth 24cm
\paperheight\pageheight \paperwidth\pagewidth
\textwidth\pagewidth
\textheight\pageheight
\hoffset=-1in
\voffset=-1in
\headheight=0pt \headsep=0pt \footskip=0pt \topskip=0pt
\topmargin=0pt
\oddsidemargin=0pt
\usepackage{fontspec}
\setmainfont{Arial}
\parindent 0pt
\parskip 10pt
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}[remember picture,overlay]
\draw [fill=red] (current page.center) circle (3pt);
\draw [red,very thick](current page.south east) rectangle (current page.north west);
\end{tikzpicture}
Content goes here.
\end{document}
```
Changing the document class to `article` and recompiling gives correct border. But I want to use my document class defined above.
**Note:** I don't want to use the geometry package!

If you would like to avoid tikz, you could draw a frame using picture mode:
```
% !TEX TS-program = latexmk -lualatex %
\begin{filecontents}{myclass.cls}
\NeedsTeXFormat{LaTeX2e}
\ProvidesClass{myclass}[2024/09/13 My document class]
\renewcommand\normalsize{\fontsize{18pt}{22pt}\selectfont}
\end{filecontents}
\documentclass{myclass}
\synctex=0
\pageheight 13cm \pagewidth 24cm
\paperheight\pageheight \paperwidth\pagewidth
\textwidth\pagewidth
\textheight\pageheight
\hoffset=-1in
\voffset=-1in
\headheight=0pt \headsep=0pt \footskip=0pt \topskip=0pt
\topmargin=0pt
\oddsidemargin=0pt
\usepackage{fontspec}
\setmainfont{Arial}
\parindent 0pt
\parskip 10pt
\usepackage{xcolor}
\AddToHook{shipout/background}{%
\setlength{\unitlength}{1in}
\put(\dimexpr-\hoffset+1mm,\dimexpr-\paperheight+\voffset+1mm){\color{red}\framebox(\dimexpr\paperwidth-2mm,\dimexpr\paperheight-2mm){}}%
}
\begin{document}

\end{document}

Concerning your second question:
You can do it in tikz if you compensate for the `\hoffset` and `\voffset` (don't forget to compile two times)
```
% !TEX TS-program = lualatex
\begin{filecontents}{myclass.cls}
\NeedsTeXFormat{LaTeX2e}
\ProvidesClass{myclass}[2024/09/13 My document class]
\renewcommand\normalsize{\fontsize{18pt}{22pt}\selectfont}
\end{filecontents}
\documentclass{myclass}
\synctex=0
\pageheight 13cm \pagewidth 24cm
\paperheight\pageheight \paperwidth\pagewidth
\textwidth\pagewidth
\textheight\pageheight
\hoffset=-1in
\voffset=-1in
\headheight=0pt \headsep=0pt \footskip=0pt \topskip=0pt
\topmargin=0pt
\oddsidemargin=0pt
\usepackage{fontspec}
\setmainfont{Arial}
\parindent 0pt
\parskip 10pt
\usepackage{tikz}
\begin{document}
\begin{tikzpicture}[remember picture,overlay,transform canvas={xshift=-\hoffset,yshift=-\voffset}]
\draw [fill=red] (current page.center) circle (3pt);
\draw [red,line width=3mm](current page.south east) rectangle (current page.north west);
\end{tikzpicture}
Content goes here.
\end{document}
```
