// Manual check in real browsers, not part of test.sh: loads the rive_native
// web build on a bare page, imports a baked fixture through the two step
// load, and advances and draws it. Needs playwright installed wherever node
// resolves it from, and rive_native built with:
//   packages/rive_native/native/build.sh wasm release --scripting_vm=both
// Run: node browser_probe.mjs [chrome|firefox|webkit] [basic.riv|trap.riv] [module.wasm]
// With a rasc compiled module it also boots a VM outside a file load, the
// way the editor previews scripts, and checks a bad module is refused.
// The bare page installs no renderer callbacks, so the first script draw
// reports a trap from inside the Flutter renderer. That is the probe's
// doing, and the page surviving it is part of what this shows.
