Delete outfitPageSSR
Oh right, we implemented this with Next.js SSR in `/pages/outfits/[id].js`, so we don't need this anymore!

/**
|
||||
* /api/outfitPageSSR also serves the initial request for /outfits/:id, to
|
||||
* add title and meta tags. This primarily for sharing, like on Discord or
|
||||
* Twitter or Facebook!
|
||||
*
|
||||
* The route is configured in vercel.json, at the project root.
|
||||
*
|
||||
* To be honest, we probably should have built Impress 2020 on Next.js, and
|
||||
* then we'd be getting realistic server-side rendering across practically the
|
||||
* whole app very cheaply. But this is a good hack for what we have!
|
||||
*
|
||||
* TODO: We could add the basic outfit page layout and image preview, to use
|
||||
* SSR to decrease time-to-first-content for the end-user, too…
