Fix prod outfit SSR by just using URLs, not build

Browse source 
Hmm, the built copy of the HTML isn't deployed with the API function on Vercel. Ok! Let's just do the same trick as we did for the dev server, and make an HTTP request.

This is fine enough for perf because we're caching this result locally to the function, plus it should be a fast CDN-cached response anyway.
