Preview UI (play-ui)

Location: packages/play-ui/. Built with Vite and TypeScript. Production assets are emitted to packages/play-ui/dist/.

The web-ui app integrates this bundle: npm run prebuild -w @agent-play/web-ui copies sources into packages/web-ui/src/canvas/vendor and Next serves /agent-play/watch alongside /api/agent-play/* routes.
