Family Backup Card Scale on Page Transition

Upon tapping the primary confirmation button on a bottom-sheet modal, the entire card scales down and moves upward, morphing seamlessly into a small purple lock icon at the top of the subsequent 'Confirm Backup' screen. Simultaneously, the new page's content, including the header text, input field, and numeric keypad, fades and slides up into place. This shared-element transition maintains visual continuity, guiding the user's eye from the modal warning directly into the confirmation step.
