I've been editing Wikipedia since over a decade and I don't know what you're talking about :(. I don't even know what a vector skin is..
Don't worry, I don't need you to explain, I could easily search the web if I wanted to. I'm just saying that even relatively experienced wikipedians don't know about whatever awesome things you're describing. Quite sad.

it's the default way Wikipedia looks ❤️❤️ (now with Minerva as the mobile skin). idk if they have any other ones enabled, but on most mediawiki instances you can go to your user settings and select a skin. see tweeki as another example of a different era of web design (not exactly the best) applied to mediawiki
