I’ll tell you my failing prompt - hopefully you can help! I haven’t tried since 4.0 / o3 / 2.5 pro came out.

I want a flowed book layout (so we have a facing page with inner and outer margins.)

I am rendering chats in the main part of the page. Chats alternate left and right alignment so it looks a bit like a text conversation. For each chat I want to put metadata (reactions, sender, time) on the margin it is aligned to.

So For a left chat, on a left page, I want to use the left (outside) margin. A left chat right hand page the inside margin.

Two things I could not get sorted: first, perfect vertical alignment between the chat and metadata, ( I think this is possible but difficult) and a persnickety bug where the first chat on each page chooses the last page’s proper margin side.

Happy to pay for an answer - I did try to hire a typesetter for this as well.
