+\section{Purpose and Scope}
+This chapter records a Docker container that compiles a
+\LaTeX\ document with \gls{texlive}, the distribution Overleaf uses to compile
+projects.\footnote{\url{https://www.overleaf.com/learn/latex/Overleaf_and_TeX_Live}}
+Like Overleaf, it drives pdf\LaTeX\ with \texttt{latexmk}, which reruns the
+engine until cross-references settle.
+
+The container is a command-line compiler. It reads a
+\texttt{.tex} file from a mounted folder, writes the PDF back to that folder,
+and exits. It opens no network ports. The image is not deployed to a course
+host or published to a registry; it was built and tested locally under WSL on
+Payton's workstation.

This covers common packages such as \texttt{amsmath}, \texttt{hyperref}, and \texttt{booktabs} while avoiding the multi-gigabyte full distribution.\\
+Build driver & \texttt{latexmk} with pdf\LaTeX, nonstop mode, and halt on the first error, so a failed compile returns a nonzero exit status.\\
+Interface & The entrypoint is the compiler; the default argument is \texttt{hello.tex}, and any other file name can be passed to \texttt{docker run}.\\
+Source and output & The document folder is bind-mounted at \path{/work}, so sources are not baked into the image and the PDF is written to the host.\\
+Privilege & The image defaults to an unprivileged \texttt{latex} user; at run time the container uses the invoking user's IDs so output files are owned by that user. The font cache is kept in \path{/tmp}, outside the mounted folder.\\
