Six URLs are baked into this page as static HTML, so they never pass through
the API where the rewrite happens - the videos and both photos have been
dead for as long as api.corben.world/files has been returning 500. The
worker signs and redirects, which works regardless of that proxy's state.
The host serves this file for any extensionless path it does not recognise, so
/v/<code> lands here rather than at v/index.html. Four lines at the top of the
head hand it on before anything renders.
Deliberately the first thing in the head and wrapped in a try, so a share link
resolves before any paint and a failure here can never take the homepage down
with it.
