Do things blazingly fast with WebAssembly

" summary

Claim: compiling Rust to WebAssembly gives native‑like compute speed in the browser — a Fibonacci loop that takes ~12s in JS runs under a second as a Wasm module. Tools shown: wasm-bindgen, wasm-pack and a Webpack Wasm plugin to compile Rust → Wasm and generate JS bindings. Demo app: a Rust‑built paint canvas using web-sys/js-sys that renders with no visible lag. Caveats: only numbers cross the raw Wasm boundary cheaply, frequent boundary crossings kill gains; streaming compilation and future GC/threads are ongoing platform work.
