/*
 * "Get the App" dialog (desktop), built by get-app.js.
 *
 * The shell is Figma's "QR - APP" (Flow dialogs 9096:11232, 8857:23974):
 * 480 wide, #141211, a 1px Primary-10 border, radius 24, padding 40, 24
 * between blocks. The shade is the paywall's (9096:12234), so the two
 * landing dialogs look alike. The store links reuse .btn / .btn--text from
 * landing.css, the same Style=Text button the design draws here.
