Previously we were using HTTP queries to keep individual function bundle sizes small, but that doesn't matter in a server where all the code is shared!
The immediate motivation is that I want /api/outfitImage requesting against the same server, not impress-2020.openneo.net. For other stuff I'm probably gonna fix this by replacing VERCEL_URL with something else, but here I figured this was a change worth making anyway.
I noticed this when Playwright was trying to draw cute ASCII art and it wasn't showing up right! Not a big deal, but it's a bit more correct to do this, so let's do it!
Things seemed to mostly work at first glance! I haven't tested outfitPageSSR because we'll need to redo it though, and also the outfit image routes aren't working anymore (vercel.json isn't how next.js works)
