1//! Crux type-generation for the shared domain (built with `--features typegen`).
2//!
3//! Demonstrates the Crux type-sharing pipeline: the core's view types are the
4//! single source of truth, and this binary emits matching JVM type definitions
5//! for the shell to consume across an FFI boundary. In this NDK-less build the
6//! Android shell hand-mirrors these types (see `app/.../core/ViewModel.kt`);
7//! wiring a real `.so` would have it consume the generated output instead.
8//!
9//! Run: `cd shared && cargo run --features typegen --bin codegen`
10//! Output: `generated/` (JVM/Java sources + the bincode serde runtime).
