I think putting the remark on the second header works better, I feel like putting it at the bottom it becomes visually as interesting as another roll. Example: https://screenshot.googleplex.com/XWsRPD5OiVo wdyt?

Hmmm, might even be better because in that case the second header block
never appears/disappears depending on the logged-in state.

hmm, not really.. it will still be hidden when loading the data in case something goes wrong we don't want to show just a header to nothing. But yeah that's the general idea

I think a toast is fine though we can change the way the toast works to 'dissappear' when the user logs in. If it is done by the way it is in the screenshot above, then it would also have to be done for ClusterFuzz data as well which would start looking too repetitive. 

Just to keep everyone on the same page, I strongly prefer the solution currently staged here: https://chrome-internal-review.googlesource.com/c/infra/infra_internal/+/450772 (screenshot: https://screenshot.googleplex.com/qj6LyzF1vsp)

Hints via UI and not toasts, as toasts are visually distracting and will fire continuously for folks who can't (or don't want to) log in, which is suboptimal IMO.
