//! WASM code generation from IR.
//!
//! Translates optimized IR into WASM bytecode using the `wasm-encoder` crate.
//! Supports two modes:
//! - **Typed mode**: when type inference succeeds, values stay in WASM locals
//! - **Fallback mode**: load/store against stack pointer globals in linear memory

// TODO: Step 5 - Full codegen implementation
// - IR -> WASM function body translation
// - Single-word module generation (JIT mode)
// - Multi-word module generation (AOT/consolidation mode)
// - Typed vs fallback mode selection
// - Function table management

        // Codegen tests will be added in Step 5
