How can I make a normal font on "qna.habr.com"?

Question

Habr Q&A

I recently discovered this awesome site, but what about the font (see screenshot) - I don’t know. I already searched the Internet for the qna.habr.com font, found something and downloaded it - installed it, but to no avail! Although, in fact, the fonts are uploaded to the site itself and there is no need to install them on a PC.
I ask for help, what should I do?
