…r mode Adds useAdaptiveFrameRate hook that detects low-end hardware (deviceYearClass < 2018 or totalMemory < 2 GB via expo-device) and battery saver mode (iOS Low Power / Android Power Saver via expo-battery), then returns a durationMultiplier (1 or 2) used to double animation durations and halve effective frame rate to ~30 fps under constrained conditions. Updates Skeleton, OfflineIndicatorProvider, PullToRefresh (RN Animated), and FilterSheet (Reanimated withTiming) to scale their timing values through the hook. Adds expo-battery dependency and 12 unit tests covering all detection branches. Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>

Resolved conflicts: - jest.setup.js: kept expo-battery mock (our addition), dropped duplicate expo-device/constants/linking stubs already present earlier in the file - package-lock.json: regenerated after accepting upstream lockfile, then reinstalling to re-integrate expo-battery Also fixed pre-existing lint warnings in upstream files merged from main: - abTesting.ts, performanceExperiments.ts, tests/services/abTesting.test.ts: switch to named imports to satisfy import/no-named-as-default + import/order Co-Authored-By: Claude Sonnet 4.6 <noreply@anthropic.com>
