## Notes

- All push notification providers follow the same interface for easy switching
- Admin dashboard uses token-based authentication stored in localStorage
- White-label dapp supports dynamic theming based on domain
- Database migrations needed for new models (AdminUser, SystemConfig, etc.)
- Frontend API calls need to be proxied through Next.js API routes or configured CORS
