// React Native entrypoint (resolved via the `react-native` package field).
//
// Hermes — the default React Native engine since RN 0.84 / Expo SDK 56 — does
// not expose a runtime `WebAssembly` global, so the normal `new
// WebAssembly.Module(...)` path used by `index.ts` throws
// `ReferenceError: Property 'WebAssembly' doesn't exist`.
//
// Instead we link a wasm2js translation of the module: pure JavaScript that
// needs no `WebAssembly` global and is instantiated synchronously at import
// time. The public API and its synchronous signatures are unchanged, so
// callers need no modification. The `pkg-rn` directory is generated by
// `scripts/build-rn.mjs`.
