# yarn-setup — install node_modules for MetaMask Mobile.
#
# Inputs:  --target <metamask-mobile dir>  (default $PWD)
#          --mode full|expo                 (default full)
# Outputs: yarn install output on stderr; exit 0 pass, 1 install failed, 2 bad args.
#
# Single device op: install node_modules. No other sequencing.
#   full — `yarn setup` (JS deps + expo prebuild + native pods/jetify). Use only
#          when a native build is wanted (launch --build / rebuild-native).
#   expo — `yarn setup:expo --no-build-ios --no-build-android` (JS deps + prebuild,
#          no native). The Metro-only remedy: native builds come from open-device.
