- Add viewport export with viewportFit: "cover" so iOS exposes
env(safe-area-inset-*) (required for the insets to take effect).
- NavRail / TopBar / main / Toaster now respect safe-area insets so content
clears the iPhone notch and home indicator in both portrait and landscape.
- prefers-reduced-motion: the media query already disabled declared animation
classes; harden it with a global transition/animation duration override and
kill the scan-line shimmer so motion-sensitive users get a fully static UI.
Verified tsc --noEmit + next build clean.
