Two fixes on the final North Star screen:
- "Rebuild" now works — a confirmation dialog was rendering behind the builder window and blocking it. It also no longer asks unless you've actually hand-typed changes to the line.
- Clearer actions: "Rebuild this mantra" is docked right under your mantra as its own step-by-step action, and the quick tweaks ("Longer / shorter", "Rewrite with AI") read as buttons instead of looking like selected toggles.
