+## Quick Routes
+
+| Task | Path |
+|------|------|
+| **UI/Frontend** | `ui-navigation.md` |
+| **When to delegate frontend** | `frontend/when-to-delegate.md` |
+| **Backend/API** | `backend-navigation.md` |
+| **Full-stack** | `fullstack-navigation.md` |
+| **Clean code** | `principles/clean-code.md` |
+| **API design** | `principles/api-design.md` |
+
+---
+
+## By Concern
+
+**Principles** → Universal development practices
+**Frameworks** → Full-stack frameworks (Tanstack Start, Next.js)
+**AI** → AI frameworks and agent runtimes (MAStra AI)
+**Frontend** → React patterns and component design
+**Backend** → APIs, Node.js, Python, auth (future)
+**Data** → SQL, NoSQL, ORMs (future)
+**Integration** → Packages, APIs, services (future)
+**Infrastructure** → Docker, CI/CD (future)
