I do not particularly enjoy an htmx-only way of doing that, because it
means that it can only work with JavaScript, but i think this is already
a lost cause, unfortunately. If i have time, i will try to make the
HTML-only form work too.
In this case, i have to put back the same row when updating or
cancelling the form, which is inside index.html. Instead of moving that
part to a separate file, i tried to define a block as a “template
fragment” and try to render that part only. Surprisingly, it works;
i am happy.
Closes#74.
