sidenotes `module` affects title page in OpTeX

Question

I was checking out this solution by Max Chernoff https://tex.stackexchange.com/a/689656/14423 about vertical alignment in margin notes with OpTeX and it works perfectly. Now, I've been trying with the commands \tit, \author, \maketoc and \part and I've noticed that no matter where I put them, such a solution affects them by making the corresponding pages have space for margin notes:

\report
\fontfam[EB Garamond]
\margins/2 a4 (1,3,2,2)in
\typosize[10/11.5]
\parindent=0pt
\parskip=1ex
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%PART
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\newcount\partnum
\eoldef\part#1{\vfil\break
   \incr\partnum _chapnum=0 _chapx % reset counters
   \vglue100pt
   \incr\tocrefnum \dest[toc:\the\tocrefnum] % destination from TOC and outlines
   \centerline{\typosize[20/]\bf Part \the\partnum:\quad #1} % Title
   _ewref_Xtoc{{0}{part}{}{}#1} % TOC line, \part has level 0
   {\nopagenumbers \vfil\break}   % single page without pageno
}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\tit My Title
\author By Me
\eject
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%Table of contents
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\nonum\notoc\sec Contents
\maketoc

    \else%
        \sidenote_side\left%
    \fi%
}
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%%
\load[sidenote]
\part First part

\def_par{\let_par=\par}

\lorem[5.]\sidenote{\lorem[5.]}

\lorem[7.]\sidenote{\lorem[7.]}
\vfill\eject
\part Second part
\chap My second chapter
\sidenote_number=199
\def\sidenote_makemark{%
    \leavevmode%
    \raise 0.7ex%
    \hbox{\typosize[8/8]\romannumeral\sidenote_number}%
}
\def\sidenote_makeleft#1{%
    \hsize=2in\relax%
    \leftskip=0pt plus 1fill\relax%
    \rightskip=1in\relax%
    \it%
    \sidenote_makemark%
    #1%
    \vskip 1cm\relax%
}
\lorem[1.]\sidenote{\lorem[1.]}
\lorem[2.]\sidenote{\lorem[2.]}
\def_par{\let_par=\par}
\lorem[3]\sidenote{\lorem[3.]}
\lorem[4.]\sidenote{\lorem[4.]}
\lorem[5.]\sidenote{\lorem[5.]}
\lorem[6.]\sidenote{\lorem[6.]}
\lorem[7.]\sidenote{\lorem[7.]}
\bye

And this produce this:

I suspect it is not trivial but what is needed so that those pages do not have space for marginal notes?

PS: I start to think that it would also be desirable for pages intended for acknowledgments, bibliography or index to also not have space for margin notes.

The issue here is all from the \margins command, and doesn't directly depend on the sidenotes (although the sidenotes do generally require uneven margins to have enough room). The solution is to set the margins to be equal where desired:

\fontfam[EB Garamond]
\report
% Offset two-sided left/right margins by default
\margins/2 a4 (1,3,2,2)in
% Switch to equal single-sided margins
\def\evenmargins{%
    \margins/1 a4 (1,1,,)in
}
% Define a really basic "part" heading
\eoldef\part#1{
    \vfil\break
    {
        \evenmargins
        \centerline{\typosize[20/]\bf Part #1}
    {\noindent \it\lorem[1]}

    {\nopagenumbers \vfil\break}
}

}
% Front matter
{
    \evenmargins
    \tit My Title
    \author By Me
\vfill

\nonum\notoc\sec Contents
\maketoc

\vfil\eject

}
% Document body
\part One
\chap One
\lorem[1-7]
\part Two
\chap Two
\lorem[1-7]
\bye

Here, we've defined an \evenmargins command that will set the margins to be equal on both sides. To make sure that it only applies locally, use it inside of a group that ends with a page break.
