Customers
Customers are minimal ordering entities, not CRM records.
Minimal entity
customer_name is the only required input. Optional fields are inline-editable
and auto-saved.
Order link
Each customer receives an immutable customer_uuid and public order link:
/order/{customer_uuid}.
Status rules
- Active: public ordering allowed
- Inactive: new orders blocked, historical orders remain visible
- Delete is not supported in MVP
