I noticed you've got a highly polished README, which looks quite impressive! Well done :)

I noticed it uses images as headlines. GitHub recently introduced dark mode. Unfortunately the images-approach doesn't work well with dark mode as pictured below.

I don't use jotai and I just stumbled upon your README by chance (in dark mode), but I thought I'd share an alternative approach that might work for you (in both, dark mode and regular mode) in case you're not familiar with it.

The repo sindresorhus/css-in-readme-like-wat shows how you can embed CSS into SVGs using foreignObject. A PR using that technique can be seen here: sindresorhus/sindresorhus#9.

I think this might help resolve the approach coming from using images only. Not sure how well it would work with READMEs displayed on npm.

In any case, I only opened this issue to let you know about a cool potential solution. This is only meant as a "hey, check this out, this might be useful". Feel free to close the issue.
