This handles the full PWA implementation cycle from manifest generation to service worker setup and offline caching strategies. It's diagnostic driven, walking you through six states from "no PWA setup" to "production ready" with specific interventions at each level. The real value is in the caching strategy advisor and the iOS quirks handling, because iOS Safari is where PWAs get weird. Works with React, Svelte, and Next.js through their respective PWA plugins. The core principle is right: offline behavior can't be bolted on after the fact, it's an architectural decision about data flow and connectivity failure modes.
