Product screens 产品界面
Designed to stay quiet under pressure. 压力上来时，界面也要保持安静。
Prepare outside the crisis 提前设置，别放进急性时刻

Action Button setup, haptic rhythm, trusted-contact status, and night default live in Prepare, not in the moment when you need one thing to do. Action Button、触觉节奏、可信联系人状态和夜间默认，都放在准备页，而不是心慌时的首屏。
