I've been looking for a replacement for that font for a long time. Do you have any suggestions?

You could just use the same font as your body copy - "Atkinson Hyperligeible" with `line-height: 0.8` and `font-weight: 700` - and remove the `font-size: .8rem;` from your `body` rule.

If you want to keep a similar style: https://fonts.google.com/?category=Handwriting
