[NTG-context] How to place "Content" and other chapter-level titles the same vertical distance from the top?

Or change the setup of unnumbered chapter titles...
Add a forced blank before there.

Maybe define your own chapter command and use a vbox.
Look at this example from the wiki:

\setuppapersize[A6][A6]
\setupbodyfont[8pt]
\def\MyChapterCommand#1#2%
  {\vbox to 4cm\bgroup
     {#1\hskip.75em #2}
     \vss
     \egroup}
\setuphead[chapter][header=nomarking, command=\MyChapterCommand]
\starttext
\chapter{test} \input tufte
\stoptext

That's not exactly what you want, but you can adapt it.

I created a chapter title style with a large number telling the chapter number, and below it the title of the chapter.

It looks like this:

---------------------
        1               <--really big chapter number
=========== <-- there is a border created by a background image between these
    How to keep  <--chapter title
    fish

This is the article <-- the article begins
about how to keep
fish
---------------------

\definefontsize[a]%
\definefontsize[b]%
\definefontsize[c]%
\definefontsize[l]%
\setupbodyfontenvironment[default]%
    [%
        a=1.200,
        b=1.440,
        c=1.728,
        l=8.916
    ]%
%

\setuplabeltext[chapter=\strut]
\setuphead[chapter][style=\ssc,placehead=yes,expansion=yes,page=yes,
numbercommand=\groupedcommand{}{\blank[1cm]},
alternative=middle,
numberstyle=ssl,
numbercolor=green,
strut=yes]

\starttext

    \completecontent

    \chapter{Test}
        \input knuth

    \chapter{Test}
        \input knuth

\stoptext

The problem I'm facing, is anytime a chapter title is called, such as "Content" in complete content, or something in the appendix, such as one of the indexes, no number is printed above, so the vertical distance from the top of the page to the top of the chapter title changes. I need these to be consistent, as there is a background image, with vertical lines.

Basically, if I call \chapter{}, it appears perfectly aligned vertically on the page, with no other settings. But when calling \completecontent or a similar title that won't get a number, because the number isn't placed, it is vertically higher on the page, but I need it to be printed the same height, as it it had an invisible number.

I've tried adding strut (the code has it in two places), but don't know if I've used it appropriately, and it didn't solve the problem.
