# Users Module

User profile management, addresses, and saved items.

## Responsibilities
- Profile CRUD (name, email, avatar)
- Address management (CRUD, default address)
- Saved items (add/remove, list with price tracking)
- Notification preferences

## Key Rules
- Users can have multiple roles (buyer, seller, admin)
- store_id links a seller/staff to their store (V1: one store per user)
- Addresses belong to the user, not a specific order
