Lol no. If you HTML is generated, it's by definition not static anymore.
Otherwise, all of the React server side rendering is static HTML.

The issue is whether they are being generated dynamically by a server. This project isn't. You run a build-tool once and then can post the .html page anywhere. It's static.
If you pre-compile the HTML using something like Jekyll, so that the webserver is just serving HTML files without any dynamic/on-the-fly processing at request time, then it's considered static.
React on the client side: static, as you still got the same files served, how they dynamically alter the page runtime doesn't count.
