Creating a page border made of text

I’m trying to create a page border that consists of text. I’ve managed to figure out how to draw the pattern I want with tikz, and have been attempting to use decorations in order to achieve this. This works fine with normal text, but I’m attempting to use the allrunes package for this border, which fails (LaTeX can’t compile that combo).

The image below showcases what I’m trying to get. The fat line with rounded corners shows how the text border should run (the line itself should not be visible). It terminates on the edge of the page on the right side.

Anyone got any suggestions as to what I could try?

EDIT:

People have suggested I post what I’ve tried. The sample below should give some idea what I’m trying to achieve. This only works with regular text. As soon as I try to convert the text to runes using allrunes (substitute the text line with text={textarc{this is just some sample text that does what I want (not runetext)}}}), compilation of the document fails.

Any alternatives to get this to work that do not use tikz are also welcome. This just seemed like the easy way.

documentclass{report}
usepackage{tikz}
usetikzlibrary{decorations.text}

begin{document}

begin{tikzpicture}
draw[
  rounded corners=25,
  decorate,
  decoration={text along path,raise=2pt,
  text={this is just some sample text that does what I want (not runetext)}}
  ]
  (4,0) --
  (0,0) --
  (0,4) --
  (4,4);
end{tikzpicture}

end{document}
