More or less, you have a directory with all your static pages, you say `firebase deploy` and then it creates a new version of your site in the firebase UI, where you can roll back to any previous version as needed. In a Hugo/whatever fashion, you'd have a script in your repo to regenerate that directory and then deploy. Still experimenting with the flow, but that seems to be the right one.
