图形的页眉和页脚

（我是乳胶新手，不知道要搜索的正确关键词。）我想在我的图形（浮动）上放置页眉和页脚线，而不是框架框，因为它们有时比整页花费的时间更长。

有什么建议么？

我希望结果看起来像这样：

和tcolorbox

\documentclass[10pt]{amsart}
\usepackage[many]{tcolorbox}

\newtcolorbox{covered}[1][]{%
    colback=white,hbox,
    blanker,
    boxsep=5mm,
    frame code={
        \draw[line width=2pt,blue] ([yshift=-5mm]frame.north west) |-
                (frame.north east) -- +(0,-5mm);
        \draw[line width=2pt,blue] ([yshift=5mm]frame.south west) |-
                (frame.south east) -- +(0,5mm);
        },
    width=\linewidth,
    nobeforeafter,

\begin{document}
  \tcbincludegraphics[
