OK. In the process of trying to fix this I started getting Netlify errors that they could not find the command ‘Zola build’ so I gave up and disconnected the repo and just dragged the /public folder onto the Build tab at Netlify. Site is up and working just fine.
It would be nice if I could still use GitHub as a mirror of my local site but then deploy ONLY the static /public folder to Netlify without any build step…
