Okay, looks like LibreOffice, when it opens a PDF file, does NOT show admonition icons properly. Not sure why. But suffice it to say, that flattening THAT WAY is not very effective if it can't even see those.

More digging, and it appears that "Print to PDF" from your favorite PDF Viewer is a thing that ALSO flattens. So I'm checking this out.

I went ahead and opened https://github.com/asciidoctor/asciidoctor-pdf/issues/1684 to either add flattening to the tools, or at least document this key phase of KDP Print publishing.
