@GunshipPenguin let's work towards moving this branch forward.

Worth pointing out that routing is in place, the entry point is not necessarily senti.social, it is possible to also enter from senti.social/trends/{name}.

When deploying this code, the webserver needs to redirect all traffic (senti.social/*) to the index page, the router I implemented will handle displaying the correct page.

It would also be helpful if trend data is never deleted in order to avoid 404 errors.
