+- **Vee-guided first-run walkthrough.** New users are met by Vee on their first Library open; the coachmark steps through a seeded demo repo (Library card → Verdict tab → Blueprint canvas) with plain narration and a spotlight on each target element. Implemented in `onboarding.js` / `coachmark.js`; copy lives in `onboarding-copy.js`.
+- **Milestone "power tour"** offered after approximately five real scans: a second coachmark sequence introducing the cross-library tools — Ask, Corkboard (Alternatives / Synergies), multi-select Compare, Radar / auto-organize, and Discover.
