I fail to see how HTMX helps. I fail to see how SSR necessarily helps too. You could be serving a page for an order that's been cancelled by the time the user sees it.

You could see that 20 years ago too, unless you manually stored the state of the form somewhere. Again, what does it have to do with HTMX, or Rect, or SSR?
