Why it exists
It gives you a demo number, an active sector and a clean view of demo calls and incidents.
That way you can show HVAC, restaurant or salon flows without fake client workspaces.
What changes when you switch sector
When the sector changes, the active demo agent changes and the incoming call behaves according to that use case.
That allows more controlled and repeatable demos.
What it is not
It is not Lera public operations or a client panel.
It is a deliberately simple demonstration layer.
