Release 3.1.0-rc.1

This is the react-native-css 3.1.0-rc.1 release candidate for Expo SDK 57. It builds on 3.1.0-rc.0 and targets the same stack: Expo 57.0.22, React Native 0.86.3, React 19.2.3, Reanimated 4.5.1 and Worklets 0.10.1.

npm install --save-exact react-native-css@3.1.0-rc.1

The rc tag points to this candidate. The stable latest tag stays on 3.0.7. Nativewind 5.0.0-rc.1 follows and requires this exact engine version. Nativewind 5.0.0-rc.0 pins 3.1.0-rc.0, so upgrade both packages together.

Bug Fixes

• babel: normalize resolved paths to POSIX so Windows rewrites work (#390)
