that solves the other problem that appeared. What about the one I
originally posted in this thread? Is it possible to pause backgrounds
on chapter pages?
one of the many ways ...
\definelayer
  [chapter]
  [width=\paperwidth,
   height=\paperheight]
\defineoverlay
  [pagebackground]
  [\directsetup{pagebackground}]
\setupbackgrounds
  [page]
  [background=pagebackground]
\startsetups pagebackground

Many thanks! It now works as expected. Just if someone finds this
thread in the future, to get the texts into the margin, I ended up
with something like the code below.
