   app-update.css — styles for the native-app "update available" prompt.
   Paired with public/shared/js/app-update.js (loaded on index.html). Only ever
   rendered inside the Flutter WebView shell. Two surfaces:
     .qa-update-banner  — soft, dismissable bottom bar (latest > installed)
     .qa-update-modal   — blocking full-screen overlay (force + below minimum)
   Uses theme.css tokens so it always matches the brand.
