@simon interesting!
I noticed that (on iOS Safari) I couldn’t use “dark night” plugin to turn it into dark mode. (Thought I could use reader mode to darken it).
Any idea if this is something you’ve explicitly blocked via a meta tag?
(My main reason for wanting to view the original as html was to aid legibility, particularly by having it in darkmode. My eyes are flaring up with photophobia and it’s literally agonising to read black on white at the moment.)
