Looks like the version of Prettier I just installed is v3, whereas our
last run in the impress-2020 repo was with v2. I don't think we had any
special config in that project, I think these are just changes to
Prettier's defaults, and I'm comfortable accepting them! (Mostly seems
like a lot of trailing commas.)
This is an important workflow for people doing art stuff, I'm told! They used to use the Classic DTI broken image UI for this, but now that that's uhh Fully Gone, let's add this more explicitly!
We add jsbuilding-rails to get esbuild running in the app, and then we copy-paste the files we need from impress-2020 into here!
I stopped at the point where it was building successfully, but it's not running correctly: it's not sure about `process.env` in `next`, and I think the right next step is to delete the NextJS deps altogether and use React Router instead.
