+- Created axios instance with withCredentials: true for session cookie auth
+- Created Vue Router with / (tree) and /login routes using lazy-loaded view components
+- Created useAuthStore with checkSession(), logout(), isAuthenticated computed
+- Created useWishStore with fetchTreeWishes(), fetchMyWishes(), submitWish(), pagination/filter state
+- Wired up Pinia + Router in main.ts, App.vue uses RouterView
+- Files changed: frontend/src/main.ts, frontend/src/App.vue, new files in api/, stores/, router/, views/
+- **Learnings for future iterations:**
+  - Stores use composition API style (setup function) not options style — more ergonomic with TypeScript
+  - Router uses createWebHistory for clean URLs — need catch-all in FastAPI for SPA routing (US-009)
