want to add authors to the blog posts but not sure what's needed. didn't see it in the starter template. just need avatar, name, and title

right now my blog structure is weird /blog/articles but i'd rather it just be /blog

if i create an interaction to show a popup on form submission, will it transfer over?

are sections that you can add to a page in shopify based on sections defined in the navigator (wf)? or are there global sections the builder pulls from?
