// QA reference: qa/open-gen-ui-advanced.md
// Demo source: src/app/demos/open-gen-ui-advanced/{page.tsx,
//   sandbox-functions.ts, suggestions.ts}
//
// Advanced Open-Gen-UI: the sandboxed iframe can call two host-side
// sandbox functions via Websandbox.connection.remote.*:
//   - evaluateExpression({ expression }) → console.log
//       "[open-gen-ui/advanced] evaluateExpression <expr> = <value>"
//   - notifyHost({ message })             → console.log
//       "[open-gen-ui/advanced] notifyHost: <message>"
// Both handlers live in sandbox-functions.ts (host page).
//
// We assert on:
//   1) page load + 3 suggestion pills render
//   2) typed "hi" prompt mounts an iframe with sandbox="allow-scripts"
//      (no allow-forms, no allow-same-origin)
//   3) clicking the Calculator / Ping suggestions eventually mounts an
//      iframe (end-to-end round-trip is skipped — see W8 note).
//
// Driving buttons INSIDE the sandboxed iframe is not reliable: the
// iframe is srcdoc-loaded with sandbox="allow-scripts" only, which in
// Playwright often blocks same-origin frame access, and the generated
// HTML layout varies between LLM runs. We therefore skip the deep
// "click a digit and assert console.log" flow and keep a mount-level
// assertion that the advanced demo wires the sandbox attribute
// correctly. Un-skip when a stable post-mount testid is added.
