Kotlin Multiplatform: Shared Logic & Compose Multiplatform

📌 Planned placeholder page: the content will be filled progressively (shared logic boundaries, source sets & expect/actual, iOS integration, Compose Multiplatform).

Planned Content

• [ ] Positioning: what to share (business & data layers) vs what not (UI by default)
• [ ] Source sets and targets; expect / actual bridge
• [ ] Gradle multiplatform project and iOS framework integration (embedding in Xcode)
• [ ] Shared-layer libraries: Ktor Client, kotlinx.serialization, SQLDelight, Koin
• [ ] Swift interop: suspend → async, Flow bridging (AsyncStream / SKIE), Kotlin/Native memory model discipline
• [ ] Compose Multiplatform as a UI-sharing option; pitfalls & checklist

Writing guidelines: see the Client Dev overview.
