The Hermes V1 Memory Fix You'll Want on 57.0.17+

The regression: Hermes V1 (the new JS engine) shipped a memory-management bug in SDK 56 that ballooned usage in apps importing 'react-native-reanimated' or 'react-native-worklets' — i.e., basically every animated app.

The fix: 'expo@57.0.17' bumps React Native to 0.86.3, which resolves the regression (plus a dev-startup slowdown).

What to do:

• If you're on SDK 57: 'npx expo install expo@latest --fix' — point release, no breaking changes
• If you're building charts/animations: this was likely your memory leak
• Watch for: apps that seemed "slow" since SDK 56 may have been fighting this the whole time

Stock Picks's mobile app was hitting it — the fix freed ~40MB baseline on the charting screen.
