/* iPad Safari: the browser's own toolbar shrinks the VISIBLE viewport, but `100vh` keeps
   reporting the LARGE (toolbar-hidden) height. The app then lays out taller than what's on
   screen, Safari scrolls the document to compensate, and the app's own top bar is pushed out
   of view — it only reappears once Safari's toolbar hides and 100vh finally matches reality.
   Pinning the shell to the dynamic viewport (100dvh, with a 100vh fallback for old engines)

   double-tap-to-zoom / pan disambiguation window before committing pointer events, which on an
   iPad means a stroke started shortly after the previous one lifts is delayed by a few hundred
   ms — or swallowed entirely, because Safari decided the two contacts were a double-tap gesture
   and never delivered the second pointerdown. That is the "I have to wait half a second between
   Apple Pencil strokes or the stroke doesn't register" bug. The app is a full-screen canvas that
   implements its own pan and zoom, so there is no native gesture here worth preserving.
   Kept as its own rule (not folded into the user-select block above) because it must NOT apply
   to .avalonia-input-element — see below.

   Widened to "#out *": naming the canvas/native-host classes explicitly missed whatever element
   Avalonia 12 actually delivers the iPad's pointer events on, so Safari kept running its gesture
   window on that uncovered wrapper and the half-second stroke delay survived the earlier fix.
