PDF Export is blank

[MarkRabey]

When I run mdx-deck-export pdf deck.mdx the resulting PDF is blank. When I follow the PDF export instructions here: https://github.com/jxnblk/mdx-deck/blob/master/docs/exporting.md, I get a PDF that doesn't display elements wrapped with <Appear>.

In a previous version, I had a workaround that no longer works. I had been able to run mdx-deck build, then serve the public folder locally and point website-pdf to that instead. However, now it seems that after running mdx-deck build, I get a 404 error at /print.
