Can I vibe code Subscribers?

Build a full-stack Web Push Notification SaaS application for an e-commerce store using Next.js App Router, Tailwind CSS, PostgreSQL (Prisma), Redis (BullMQ), and Node.js `web-push` library.

1. DATA MODEL:
- Store: id, name, domain, vapidPublicKey, vapidPrivateKey
- Subscriber: id, storeId, endpoint, p256dh, auth, browser, os, ip, status ('active', 'unsubscribed'), createdAt
- Campaign: id, storeId, title, body, iconUrl, targetUrl, status ('draft', 'scheduled', 'sent'), scheduledAt, totalSent, totalClicked
- Event: id, subscriberId, type ('impression', 'click'), timestamp

2. CLIENT SDK & SERVICE WORKER:
- Provide a embeddable JS snippet that registers `/sw.js` on the merchant's store domain.
- `sw.js`: Listen for `push` events, display payload using `self.registration.showNotification(title, options)` with custom actions. Handle `notificationclick` to log click events and open `targetUrl`.
- Implement a two-step opt-in modal prompt that captures browser permission and sends subscription JSON (endpoint, keys) to API route `/api/subscribe`.

3. BACKEND & CAMPAIGN ENGINE:
- Secure VAPID key pair generation on store onboarding using standard `web-push.generateVAPIDKeys()`.
- Build campaign scheduler UI to trigger immediate or scheduled push broadcasts.
- Use BullMQ queue to chunk subscribers (100 per worker batch) and execute `web-push.sendNotification()` concurrently.
- Catch status 410 or 404 response errors from browser push gateways and automatically mark subscriber tokens as 'unsubscribed' in the DB.

4. SHOPIFY ABANDONED CART WEBHOOK:
- Expose POST `/api/webhooks/cart-abandoned` receiving cart payloads.
- Match customer email or session cookie to stored push token, enqueue a push job delayed by 1 hour with campaign copy 'You left items in your cart!'.

5. DASHBOARD & ANALYTICS:
- Dashboard displaying total active subscribers, push click-through rates (CTR), and campaign history.
