The h1, h2, etc tags are intermittently Lora on the Handbook site. In page h2s like here: https://planet4.greenpeace.org/start/taxonomy-categories-tags/

but also inside of blocks like here: https://planet4.greenpeace.org/start/vision-and-design/

Not sure why we are overriding font at all for the handbook: https://github.com/greenpeace/planet4-child-theme-handbook/blob/master/style.css
