You could deploy HTMX on top of any static site generator and get literally the exact same experience? Your portrayal of any of this as 'novel' just comes across as naive. The technology already exists, I agree its underutilized, but this could have been an advocacy post instead of reinventing wheels that are already quite well made.
HTMX is more like "jQuery on steroids", but Nue is a frontend development framework with universal HMR support. Think Next.js but slimmer. Different tools for different needs.
