iOS home-screen PWAs IGNORE viewport maximum-scale (Apple disabled it for accessibility), so
the maximum-scale=1 that stops auto-zoom in the Capacitor WebView does nothing in the PWA — it
still zooms on input focus. Real cross-platform fix: make every focusable text field 16px on
mobile (the composer was .92rem). autoGrow's empty-guard keeps it one line.
Also the PWA has no Capacitor Keyboard plugin, so the composer never lifted above the keyboard
("not the same keyboard"). Added a VisualViewport-based lift for non-native clients (browser +
PWA); native still uses the plugin. >100px threshold ignores the Safari toolbar.
