# Syncs React sample packages from npm into samples/:
#   - @salesforce/ui-bundle-template-app-react-sample-b2e
#   - @salesforce/ui-bundle-template-app-react-sample-b2x
#
# Opens a single PR when either (or both) npm package versions have changed.
# Same steps as running locally: npm install && npm run sync-react-b2e-sample
# and npm run sync-react-b2x-sample.
#
# Uses IDEE_GH_TOKEN (bot) for checkout and PR creation; same pattern as
