Add font-weight and font-familty setting

[kuon]

Under linux, the font rendering is different and with the current settings, it is very thin (look at screenshot).

I think it would require quite some work to find some universal font setting. Instead I propose to add an advanced setting to specify font-weight and font-family css directly.

Strange it is this thin!
Which browser are you using?

As a comparison on windows it looks like this:

May you try to inspect the page and disable this CSS property?

I made the text a little thinner on dark mode so the text doesn't look "smudged".
But it really shouldn't look that thin.

Yes with font-weight: 400 it's similar to windows.

I did investigate a little bit:

• I have the inter font installed, and font-weight: 250 is not in it, so it falls back to 200. If I use font-variation-settings: 'wght' 250; CSS instead of font-weight it correctly generates a weight of 250 using the variable font variant of my installed font. (but this weight still look a bit thin, image attached)
• Windows fonts rendering is known to be a little big bolder/smudger than linux and linux usually do not need the "trick" to reduce boldness on dark background

Actual 250 weight rendering:

Normal 400 weight rendering:
