This seems like a huge improvement to me. I would have been a lot less confused. Thanks for working on this!

Nice cleanup of the h/g/p references! I think the page could go a bit further though — right now some of the "project" → "instance" swaps read a little awkwardly, and the page still frames things around a grouping construct rather than the current account/IAM model.

I put together a suggested rewrite reframing it around accounts, service instances, and IAM (access groups, resource groups, Enterprise accounts):

Happy to open it as a PR against your branch if that's easier to work with.
