 ### Phase 7: Setup Wizard
 **Goal**: A new user can set up their budget template in under 3 minutes by following a guided 3-step wizard with pre-filled common items and a live running balance

   3. A "remaining to allocate" balance updates live as items are checked or unchecked in step 2, showing income minus the sum of selected item amounts
   4. User can click "Skip" on any individual step or "Skip setup" to exit the wizard entirely without creating any data — and lands on the dashboard
   5. Completing the wizard creates a populated template from selected items — user lands on the dashboard with their template in place, and refreshing the browser mid-wizard restores the wizard at the correct step
