// On the phone bare-kit passes EXACTLY the args the shell gives, so Bare.argv is

// ..., args.size(), args)). On a desktop `bare lib/worklet.js <storage>` gives
// [runtime, script, storage]. 0.1.0 required argv.length > 1 -- true only on a
// desktop -- so on the phone the worklet loaded and then never started.
