/*
 * FamilyOnGuard — shared shell.
 *
 * Design rules, all downstream of the product:
 *   - Dark by default. This app is opened at night, in the street, and a white
 *     screen lights up the face of someone who may not want to be seen.
 *   - One thing on screen at a time. During an alert the person cannot read.
 *   - Nothing essential requires looking: the button is found by feel (it is
 *     the whole lower half), confirmation is a vibration.
 *   - Touch targets ≥ 56px, text ≥ 17px. Cold hands, moving, adrenaline.
 *   - Safe areas everywhere: this runs full-bleed inside a Capacitor shell.

 * "Appeler le 17" stayed on screen during an alert that had found somebody,
 * and the cancel button would have stayed after a responder took it, offering
 * an action that could only be refused. Every `el.hidden = true` in this
 * codebase depends on this one line.
