Routed screens are transparent fragments rendered into the shell's single Scaffold. A screen pushed on top (e.g. device detail) was therefore see-through, leaving the screen beneath visible as it slid in, and the fade page ignored secondaryAnimation so the covered screen sat frozen instead of parallaxing out. - Paint each routed page opaque (theme surface) so pushes cover cleanly. - Drill into detail screens with a CupertinoPageTransition slide; the covered page parallaxes out via the same route animation, so both move in lockstep on the native iOS curve. Tabs keep their crossfade. Co-Authored-By: Claude Opus 4.8 <noreply@anthropic.com>
