// `interactive-widget=resizes-content` makes Android Chrome shrink the
// layout viewport when the on-screen keyboard opens, matching iOS
// default behavior so `fixed inset-0`-centered modals (passphrase
// prompt, group picker, etc.) sit above the keyboard. Other browsers
// (Safari on macOS/iOS, desktop Chrome, Firefox) emit a console warning
// when they encounter the unrecognized key on every page load — so we
// only attach it on Android.
