I'm interested, but... could I convince you to change the font and the colours into something that makes the site readable? Very thin font, light on dark, very little contrast is about the worst case for readability.
PS: Firefox's and Chrome's reading mode is probably the best quick workaround. When opening a post in Firefox, I get a Reading Mode button in the navbar, and for Chrome it's in the new sidepanel.
Another thing that's hurting readability is monospace.
I stayed for the content but the colors and the thin monospaced font didn't make it a pleasure. I have returned regularly over the years because I like the content so much.

Do you have retinal detachment? It can cause high contrast to be unpleasant to the point of being painful.
