Got it

The HTML comes through in the Elements section of the page. It didn't show in an initial glance at the immediately accessible most basic source view in Firefox. But Chrome kept track of it through some more advanced source interface. I'm sure I could have got it in Firefox too, I'm just not set up for development.
So the trick is to copy the core text as HTML, which is possible.
Next step is to apply the CSS.
Then save it as something that can be converted to epub or PDF.
I grabbed the stylesheet from the site, and imported into Dreamweaver, so now I just need to fix up the styles a bit.
Then repeat it x66 for each book in the Bible.
It was not easy, but certainly possible without doing anything particularly complex.
The CSS comes out a bit funny, but it shouldn't be a problem to fix.
