" summary

Three demos show a runnable monorepo: a KMP quiz app sharing business logic via expect/actual, Compose UI rendered on Android, desktop and iOS (Android/desktop stable, iOS beta, web alpha), and a Ktor backend that collects results and serves SVG charts generated with DataFrame + cand. Implementation details: KStore/case‑store for multiplatform persistence, Kotlin flows and coroutines, hot reload on server/desktop, Jupyter notebooks with the Kotlin kernel for iterative plotting, and use of Ktor server and Gradle modules.
