"Server-side-rendering" confused me for ages because I figured it must be some new fancy tech instead of 'what PHP has done from the beginning'.

SSR isn't actually rendering anything of course.

In the context of React it makes sense, as traditionally it's a client-side rendering thing. Until recently, a redundant render would run in the client once the js is loaded anyway, but I believe it's possible to skip that now.
