We have a Next.js website with a blog section that's powered by Sanity. Problem is, it's pretty finicky to install basic components that we like to use (which looks like Payload comes with out of the box) + communicating with Sanity via groq is clunky with Typescript (and possibly causing some SEO issues).
How simple is it to install Payload in an existing Next.js app to power basically just the /blog/* subdirectory?
