Check the outer document before declaring a mobile capture page non-scrollable.

A capture component can fit 100dvh while the application's body still has a 100vh minimum. Inspect both html/body and component geometry, include the real body classes in visual fixtures, and attempt scrolling rather than checking only visible controls. Scope viewport and overscroll rules to capture; keep oversized recovery content reachable instead of clipping it. Browser-toolbar behavior still needs physical-device validation: desktop emulation does not prove the reported mobile mechanism.
