        <source xml:lang="en">Replace the front cover content with a single full-bleed image. See [Full Page Cover Images](https://docs.bloomlibrary.org/full-page-cover-images) for information on sizing your image to fit.</source>
        <note>BookSettings.CoverIsImage.Description.V2</note>
      </trans-unit>

Should v1 above be marked obsolete? Or not yet because we aren't sure we are going with this approach?
Seems like we might as well then everything can be backed out together if we decide to revert.

        public bool FullBleed =>
            PageSizeSupportsFullBleed()
            && BookInfo.AppearanceSettings.FullBleed

Are we deciding for now not to handle migration? Do we have a note about that somewhere?

            // Device sizes do not support full bleed
            return !sizeName.StartsWith("Device", System.StringComparison.OrdinalIgnoreCase);

This isn't quite accurate. It should be kept in sync with ConfigureFullBleedPageSize.

        {
            var layout = GetLayout();
            var sizeName = layout?.SizeAndOrientation?.PageSizeName ?? "A5";

If we can't determine page size, it seems like we should return false?

I noted in the card several issues that I did not address, since John indicated that he wants to quickly get this working and see if it helps solve various problems. Effects on 6.2 was one of them.

I suppose so. Weird case; we always set some page size, IIRC.

I think the AI did it, and I went along because I thought we now handled all the others. I guess that's 6.4...or maybe I only got part way to handling them all. Done.
