Notary PWA v1
Embedded Files
**PWA (Progressive Web App)** = **installable web app** — runs like a native app, but is just a website.
---
### What it does:
| Feature | Description |
|--------|-------------|
| **Installable** | Add to home screen (iPhone/Android) → opens full-screen, no browser bar |
| **Offline** | Works without internet (after first load) |
| **Push notifications** | Optional (not needed here) |
| **Fast** | Cached locally |

### Your `quantumvault-notary-pwa`
Same **web version** (HTML/JS) — but **installable**.

#### 3. `service-worker.js`
```js
const CACHE = 'qv-notary-v1';
const FILES = ['/', '/index.html', '/manifest.json', '/icon-192.png', '/icon-512.png'];
self.addEventListener('install', e => {
e.waitUntil(caches.open(CACHE).then(cache => cache.addAll(FILES)));
});
self.addEventListener('fetch', e => {
e.respondWith(caches.match(e.request).then(resp => resp || fetch(e.request)));
});
```

#### 4. Register SW in `index.html` (add to `<head>`)

window.addEventListener('load', () => {
navigator.serviceWorker.register('/service-worker.js');
});
}

**Done.**

- **Offline**
- **Cross-platform** (Android, iOS, Desktop)
- **No app store**
**Best of all worlds.**
Want **hosted version**? Say `host`.
