/*
 * install-app.css -- Permanent "Install app" surfaces
 *
 * Two surfaces, mounted by /assets/js/install-app.js:
 *   - hero variant (homepage, near the Plan-your-trip CTA)
 *   - footer variant (interior pages: dashboard, planner, companion, etc)
 *
 * Plus an iOS Safari fallback modal that explains the Share-menu route.
 *
 * Token-only, theme-aware (uses theme.css palette). No hardcoded colour
 * values. Hidden by default; JS unhides once it has confirmed the page is
 * not running in standalone mode and either beforeinstallprompt fired or
 * the user is on iOS Safari.
