User story:
When you paste a link to a a karrot URL into a chat app, it creates a preview, but the preview text is always just the default Karrot home page text, not the info about the link.
In the case of sharing a public activity link it would be very helpful to have the preview have the basic information about the public activity.
This is requested by Dave in Robin Foods.
Complexity:
I wrote about some of the technical details here Support link previews · Issue #2617 · karrot-dev/karrot-frontend · GitHub
It’s actually surprisingly complicated due to our architecture.
Currently my preferred solution would be to introduce SSR (server-side rendering), which would require running a nodejs process to serve up a template index.html file, and also switch to normal routing urls:
Current URLS look like: https://karrot.world/#/group/1
Normal URLs would look like: https://karrot.world/group/1
Would also improve SEO ability

Consider the priority of it, and schedule it
