Hi Alex,
Wow, I'm envious. For you, lore let those gigantic attachments through.

I see what you mean.
One bet is that I messed something up here and Deri's first or second
hypothesis will be correct.
Here's mine.
You might need to set a register I added in this commit.
commit 5fbc22d022c07f517bc83aa9b8c97ea5536efd18
Author: G. Branden Robinson <g.branden.robinson@xxxxxxxxx>
Date: Sun Mar 3 23:57:38 2024 -0600
[man]: Add `an*bookmark-base-level` register.
* tmac/an.tmac: Add experimental feature to support increasing the base
level of PDF bookmarks. Define register `an*bookmark-base-level`,
initialized to zero.
(PT): Add 1 to it when producing document bookmark.
(SH): Add 2 to it when producing section heading bookmark.
(SS): Add 3 to it when producing subsection heading bookmark.
I don't know what you're using to produce the chapter headings in the
navigation panel, but that likely needs to be at level 0 (or 1,
depending on the convention the PDF spec uses).
I added the foregoing feature because it was obvious to me that someone
might want to incorporate a man page collection into a larger work.
I admit I didn't think of the chapter organization application.
So you'd likely do something like this when building with groff Git
HEAD.
'-r an*bookmark-base-level=1'
Let me know if that works out.
The foregoing is not documented because it needs field testing. Now
maybe it will get some.

This is very good news.
