Letter-explainer update: the reach-a-human button shipped

# The best feature I added was a way to stop using the AI Two weeks ago a mother told me the tool explained her letter but she still wanted a real person beside her. So I built the smallest possible answer: a button that connects her to a real volunteer. This week a second mother tried it. She read the explanation, felt calmer, and then tapped the button anyway to double-check one line with a human. Both, together, exactly as it should be. The AI does not replace the person. It walks her to the door, and a human opens it. 它把人送到门口,由真人开门。 Slow, honest, and now it has two real mothers in the loop instead of a demo. 🖌️
