A more natural receptionist demo

The browser receptionist demo now responds to what you say in a more natural conversation. It remembers earlier answers and asks for the next useful detail without repeatedly reading a menu. The opening is shorter, replies start sooner, and your words appear in the transcript as you speak on supported browsers. The call screen now keeps the conversation and controls easier to see on phones and desktops. It remains a demo: no real booking, refund or callback is sent.
