   PWA login — single-column, Netflix-style mobile sign-in.

   Activates only when the installed PWA is launched on a phone-sized
   viewport (body[data-pwa="true"] is set by pwa-register.js when
   display-mode: standalone matches). Browser tabs — including mobile
   browser tabs — keep the full two-pane hero layout.

   The hero panel, long feature list, and fineprint are hidden; what's
   left is brand + heading + Google button + three compact info chips.
   Background is a dark gradient matching the splash so the handoff from
   launch animation → sign-in feels continuous.
