Neither platform layer checks the OS reduced-motion preference: grep finds no accessibilityReduceMotion (iOS) or animator-duration-scale/remove-animations handling (Android template) anywhere. All nav transitions (:push/:pop/:reset) animate regardless.
Proposed: gate at the native layer, not the BEAM — when iOS UIAccessibility.isReduceMotionEnabled or Android's animation-removal setting (Settings.Global.ANIMATOR_DURATION_SCALE == 0) is active, render every nav transition as :none while leaving the app's declared transitions untouched. That keeps app code motion-agnostic and matches how the web side handles it (useReducedMotion gating on every animation). Small, self-contained: one condition in iOS navTransition/navAnimation, one in the template's AnimatedContent transitionSpec.
Context: surfaced while choosing tab-switch transitions for a downstream app; :reset already provides a 250ms cross-fade on both platforms, so transition VARIETY is covered — respecting the user's motion preference is the remaining gap.
