As someone with friends who use screen readers, I notice when sites are close, but not quite there. Many websites are just a lost cause, but this is very close to very accessible :)

The main limitation is it would be nice if the sections were labelled, either with a <hx>, or <section>, to make it easier to jump around the page.

The ascii art gets read, which is a bit annoying, aria-hidden="true" will make the ascii art not get read out as text.

The best option is to try out with a screen reader -- on both windows + mac a decent screen reader is built in (it's worth best with the default browser, safari on mac, edge on windows). I'm not expert on screen reading on Linux.
