@slightlyoff I read the article, but I still struggle to understand what technology/ library / framework I should be using to do progressive enhancement well. In one section you mentioned htmx and hotwire (I'm reluctant to use hotwire, because I use HEY, and it's rubbish and I regret it)
You've mentioned lots of SPA platforms, which I'm trying to avoid. The Gov UK site seems similar, in that it tells me general approaches, but won't recommend specifics.
