Typeface used in Leo

I wanted to provide feedback that the current typeface used for Brave Leo could be improved for on-screen reading, particularly when using the Dark theme. The legibility issues are more noticeable against the dark background. Specifically, the letter spacing is a bit tight which affects legibility at smaller sizes.

Updating the font to one that is designed to work perfectly on screen, or at least widening the letter-spacing would be very welcome.
