Text is too light and too thin to read #7

Hi,

Thanks for the project! I really enjoyed its vibe.

Unfortunately, I'm having some trouble reading the typography due to its combination of lightness and thinness. The default paragraph colour is #797E83 on white, which is lighter than the minimum recommended #777 brightness (source: http://mrmrs.io/contrast/).

As for the font, I think it might be a Gecko rendering thing but some of the stems on smaller text have a width of less than 1 pixel, so they're getting blurred.

My env is FF 43 on Windows 10, 1366 x 768

Thanks again for your work on this,
Ste
