Feature: Improve SEO

[megoth]

The site is currently written using Vite and react-router-dom, and no form of SSR (Server-Side Rendering). This means that there's one HTML for each page, having the same title, description, etc for meta fields.

This is less than optimal, but requires a bit of work to get to properly work with the current setup. I've worked a bit using Rakkas, but didn't get to the end successfully (I've pushed my work to the branch ssr-rakkas, but it's quite outdated now).

There's also a recent addition to Remix that allows you to use Vite, but the integration is unstable, so not sure if I want to try that route.
