I'm not sure why so many people seemingly fall into the trap of trying to find one tool and then use that absolutely everywhere. I mean, I'm familiar with it as in "it's fun" as I used Nix as a framework for a static website builder, but I keep seeing people making those sort of choices professionally too. Like when React first became popular, then suddenly people try to jam it into absolutely everything, until they slowly walk back and then after some years agree that maybe it's good for some things, not for everything and not as a default.
And, yeah, HTMX is truly great for sites with limited interactivity. You really, really do not want or need a full React Leaning Tower of Pisa stack for a simple presentational website.
