Relative size and weight of post title vs menu bar

Hey. Thank you for your work on the theme. It looks great!

Something my friend and I noticed while testing this theme out: on wide screens, the larger size and heavier weight of the post title on the home page stand out very far and overpower the links in the top menu bar.

I'm curious whether others think about this. Do you think this is something that should change? I can put together a branch with some changes, if desired.

Some possible changes to reduce this effect:
- Reduce font weight of post title, possibly to `500`.
- Increase font size of top menu bar, possibly to `2.0rem`.
- Increase font weight of top menu bar, possibly to `600`.

I tried these out interactively in Chrome's inspector. Any of them could potentially reduce the perceived disparity. Then again, that's just what I see, and I'm wondering if others see it the same way.

Thanks!
