The Shepherd is a guide that lives across the Studio — bottom-right of every page once you're signed in. He's not a chatbot. He's a named guide who:
- Remembers your project, message, ICA, and where you are in the funnel
- Knows every tool in the Studio and what each one does
- Cites Knowledge Base articles when relevant
- Suggests the right next step instead of generic "have you tried X?"
