How can I suppress headers and footers on blank verso/trailing pages

As for the trick used here, very briefly, because a pagebreak is also an element, then you can re-define it to also raise a “start” and an “end” flag (metadata), and return “yes, the page is empty”, if you are currently between any of these two flags.

I was actually also confused at this. A neat trick. So pagebreak is not just a command, but an element that can span a long way, even a whole page?

Is `pagebreak` just a command, or also an element?

Continuing the discussion from How can I suppress headers and footers on blank verso/trailing pages: We use a show rule “trick” to make pagebreaks detectable. // make pagebreaks detectable #show pagebreak: it => { [#metadata(none) <empty-page-start>] it [#metadata(none) <empty-page-end>] } @Andrew was confused about this, because he thought a pagebreak() was just a command.
