This is awesome: thanks for these resources! We'll take a look at Cloudflare Browser Isolation for sure. We've played with screenshot tools at specific viewport dimensions etc, but it's not often the right fit for when we're doing interactive frontend responsive updates. That aside though, the screenshot APIs could be a great integration to be able to download/save screenshots of specific viewports.

DevTools has a list of default viewport sizes, but they change from browser release to release. Is there a better way or an existing [YAML] file schema to generate a list of viewport configurations to import into DevTools?

We looked into this, and we couldn't find a way to do so, but we've open sourced the data (here: https://github.com/bitcomplete/labs-delta-viewport-tester-vi...) so if you are able to find a way to do so, that could be a great option.
