Both chat branches touched the same places. The grounded answer keeps the
lines read from the code and takes the reason of a dropped sentence; the
divider says "Back to" for a returning topic and "New topic" in the
language of the turn otherwise; examples follow the kind of the selection
and the hint offers no model. The new tests of the behaviour branch now
expect the reworded texts, and the German follow up answer quotes the
prompt like the other German hints.
