Uses Web Workers plus Comlink to offload a 3,000-item sort so the UI animation keeps running instead of freezing; builds a WebAssembly function with AssemblyScript to run Fibonacci measurements that show seven times faster on first run and near-parity thereafter; uses the CSS Paint API worklet to render backgrounds and QR codes without blocking the main thread; implements a Service Worker that decodes WebP on the fly so unsupported browsers still display images. Concrete tools, numbers, and working prototypes determine whether to watch.
