why keep the chrome/ directory structure? Why not just put everything in /docs/css and /docs/js ?

✅ Spot-checked a bunch of pages and they all looked pixel perfect. And it looked like all the shared chrome was correctly removed and the css correctly ported.

🤔 Only potentially blocking issue is all the stuff still in public/{js,css}/ since a) it's misleading having different environments load different assets and b) because a lot of js files have two copies in this repo now.

ℹ️ Just making a note since I don't see it mentioned in the PR description or linear issue. There's a PRODIGIOUS amount of css that can be removed now. I think it makes sense to clean it up in a separate PR/issue, but it'd be good to link to the issue from this PR (and create it if it doesn't exist already).

These js files that were added already existed in the repo, just at public/js. And they weren't removed there so we have two copies of all of these now. Also, I still see a lot of references to "/js/...", e.g. cookie-consent.js loads "/js/marketing-hotjar.js" which in production will point at something different than local/staging.

There's still one css file left in public/css: public/css/inkeep.css. Its js file (inkeep.js) is also not accessible by /docs.
