[NTG-context] fancy chapter setup

[Henning Hraban Ramm]

Hi all,
I’m trying to setup a book layout where each chapter begins with a quote and an image on the left page, followed by title and text start on the right page.

While the quote & image thing works, I can’t get the title on the right page, ConTeXt always puts it right of the image, even if that’s as wide as the text width. \page[right] doesn’t do anything.
Where’s my mistake?

There are also chapters without that intro, therefore I use \doifnot{\structureuservariable{subtitle}}, but those should also start on a right page. I could also use a different section name. But I don’t think that’s the problem.

(The page number should appear on the right page; it wouldn’t hurt on the left page, but the chapter title should only appear on following pages.)

Best, Hraban
