Thank you for this. I have not come across that validator before.
It did reveal three errors. I had used text-decoration: normal instead of text-decoration: inherit.
Which then begs the question, why did three levels of checking not capture this?
1 - values are coloured blue in the stylesheet (in calibre) when unknown values are entered
2 - CheckBook did not flag it
3 - epubCheck did not flag it.

So I did correct those three errors. Sideloaded the epub again, but it still did not display.

Sure. It is attached.
