About tab. What Stelow is, what each track is for, a Learn-more button to the stelow repo, and the running build stamp — product identity in exactly one place instead of the Build header.
Explore onboarding tour. The Explore board joins the shared first-run Tour (one stage / catalog / artifact), like Inbox, Build, and Research.
