/* App-shell mode (installed PWA / Android TWA): hide web-only affordances inside the app view. These live in #view-app, so unlike the marketing nav (which sits in #view-landing and disappears with it) they need to be hidden explicitly. The "Back to site" link can't actually reach the marketing site here anyway — the route() guard in js/app.js bounces any landing route back to #/app — so in the app it's just a dead end. Hidden from first paint via the pre-paint [data-app-shell] flag set in index.html's , so it never flashes in. */ [data-app-shell] .back-to-site { display: none; }
