A unique tracking link is created for every order and shown only on
this confirmation screen — it is not included in the WhatsApp message,
and there is no customer login or order-history page, so a customer who
doesn't save that link has no other way to look up their order again.
The tracking page shows a status stepper (Pending → In Progress →
Completed, or a separate Cancelled state) with the full itemized order,
totals, delivery address, and a "Need help?" WhatsApp/call shortcut if the
owner has WhatsApp set. It updates automatically as the owner changes the
order's status in the dashboard — nothing needs to be re-sent.
The owner can turn tracking off entirely (Settings → Notifications); it's
on by default.
