/* Life OS · the homepage, made to look like the app.
   22 Sept 2026: "update it, polish it, make it look like the iOS app. Full
   screenshots, animations, extremely cool animations."

   Everything here reads the design-system tokens, so it follows the site's
   light and dark themes. The phones stay dark in both, because the screens in
   them are the app's own dark screens. */
