summary
Shows a working polyglot prototype: a JS consumer compiled with JS-on-Wasm (javi) calls a Rust date-formatting crate built with wit-bindgen and chrono/chrono-humanize, linked at runtime with wasm-link and run on wasmtime. Static build is 2.2 MB and ~323 µs; dynamic linking yields 900 KB and ~106–160 µs (roughly 50% size and latency savings). Debuggability and higher memory use from multiple linear memories remain unresolved.
