// Android reads release.config.json directly from build.gradle, but Xcode keeps
// MARKETING_VERSION / CURRENT_PROJECT_VERSION inside project.pbxproj, so they have to be

// is the whole point: a build number that silently disagrees between platforms is how you
// end up with "1.4 on Android, 1.2 on iPhone" bug reports that nobody can reproduce.
//
// Run with --check to verify without writing (used by release.sh as a pre-flight).
