The hub loads uf.html and mbr.html from the same folder, which browsers
block when a page is opened directly from disk (file://).
Put index.html, uf.html and mbr.html in one folder and serve
them — any static host works (Netlify, Vercel, GitHub Pages), or locally run
python3 -m http.server in that folder and open http://localhost:8000.
