Live prompts during a cold call

Build live prompts during a cold call.

Context: Listens to the call as it happens and puts the next line on screen. The
prospect raises price, you get the objection handler before you've finished
hearing it.

Sales enablement tools already do this after the fact — they score the call and
tell you what you should have said. Useless in the moment, which is the only
moment that matters.

Three hard parts, none of them the transcription.

Latency. A suggestion that arrives two seconds late is worse than none, because
you've already started talking. It has to be ahead of you, not behind.

Reading without derailing. If you're looking at a screen you're not listening,
and the prospect hears it. Whatever appears has to be glanceable — a few words,
not a paragraph.

And consent. Recording a call has different rules in almost every jurisdiction,
some requiring both parties to agree. Build that in from the start or the
product is unsellable to exactly the companies who'd pay for it.

Requirements:
- Ship the smallest version that delivers the core value above, nothing more.
- Pick a stack you can deploy in a day, and state the choice before writing code.
- Handle the empty state, the error state and the offline case explicitly.


Start by listing the screens, then build them one at a time.
