You can change the wiki view mode at the bottom of the page (mobile/desktop).The wiki is heavily broken, it's always stuck on mobile mode, and some of the pages are on desktop mode, and while on mobile mode all the text and sections are out of order or merged over one another. This seems to be an a issue for every Paradox wiki which is broken on the main page.
Is there a way to force desktop mode?
Here's an example, this is now they normally look

The Stellaris Wiki is also broken, and for CK2 it's the normal front page, but all the sections you click on are broken and in the mobile version. This has been broken like this for the past year.
It could be that it was clicked on by mistake at one point. The wiki remembers the last mode pick and keeps using it (done per wiki).
