Pwototyping
summary
Claim: web pages built with Jamstack, a manifest.json, Workbox service workers and careful pre-rendering can first paint within 30ms and routinely fool users into thinking they are native apps. The prototype uses add‑to‑home‑screen, preloaded fonts and images, deferred/type=module bundles, and offline caching; an Ethereum buy flow runs as separate page loads and still feels instant. A key gotcha: manifest start_url = /index.html keeps iOS links inside the app. Workbox service worker caching handles background precache and dynamic assets.
