tishlang_compiler_wasm 2.0.2

//! Tish compiler exposed to JS via wasm-bindgen.
//! Compiles single source string → bytecode (base64) or JS. Used by playground, REPL, try-it pages.
//!
//! `compile_to_js` / `compile_to_js_with_imports` use Lattish-style JSX lowering. Prepend a compiled
//! **Lattish.tish** runtime (same as playground `lattish-runtime.js`) so the iframe/script scope has
//! hooks and the JSX helpers; source files do not need to import the JSX helper by name.
