//! # wasm adapter — thin `wasm-bindgen` wrappers
//!
//! Each function here mirrors one of the crate's boundary functions
//! but takes and returns JSON strings so the JavaScript side can call
//! them directly without any custom `serde_wasm_bindgen`
//! serialization. All logic still lives in [`crate::logic`] and
//! [`crate::boundary`]; this adapter exists solely to expose the
//! calling convention JS expects.
//!
//! Enabled with `--features wasm`. The Rust callable form is
//! unchanged; downstream WASM builds do
//! `wasm-pack build --features wasm`.
