Adding IndieWeb support to my static Hugo blog

I recently read Andros Fenollosa’s article I joined the IndieWeb, here’s what I learned and immediately went down the same rabbit hole.
I had seen the term IndieWeb before, but I always assumed it meant a vague preference for personal websites over social networks. Something nostalgic, maybe a little idealistic, but not necessarily technical.
It turns out there is a very practical side to it: small standards that let independent websites describe their content, receive links and reactions from other sites, and connect to social networks without giving up ownership of the original content.
