Subject: src/app/markdown: no-js xeblog-conv support

Thanks to the meddling of @fasterthanlime, I now use lol_html[0] to
parse the <xeblog-conv> elements on the server side instead of on the
client side as an HTML custom element. I will be using this strategy in
the future to expand my blog's functionality and make the christine dot
website cinematic universe stronger.
