Looks pretty nice! I installed it and gave it a go. It definitely looks neater on the landing page demo than it does on my monitor; I suspect it's because my monitor is running at 1440p.

Also, it appears a little broken on maths-heavy pages. See https://en.wikipedia.org/wiki/Fourier_series.

Multi-line equations get displaced by the pictures on the side, some even appearing with a horizontal scroll bar. Lots of strange white-space in some equations.
