Can I vibe code Instapage?

Build a full-stack Landing Page Engine using Next.js (App Router), Tailwind CSS, PostgreSQL, and Vercel Edge Middleware.

1. DATA MODEL
Create a Prisma schema defining:
- Page: id, slug, title, status (draft/published), domain, current_variant_id, created_at, updated_at.
- Variant: id, page_id, name, weight (0-100), content_json (JSON structured layout), CSS_overrides.
- DynamicRule: id, page_id, query_param, target_key, default_value.
- FormSubmission: id, page_id, variant_id, payload (JSON), IP, user_agent, created_at.
- AnalyticEvent: id, page_id, variant_id, event_type (view/conversion), created_at.

2. DYNAMIC TEXT REPLACEMENT & EDGE ROUTING
- Implement Next.js Middleware to read incoming URL query parameters (e.g., ?utm_keyword=shoes).
- Intercept requests to /[slug], select a Variant based on variant weights for A/B testing, and pass the selected variant via headers without redirecting.
- Replace placeholder tokens (e.g., {{utm_keyword}}) in `content_json` server-side before rendering HTML to prevent Client-Side Layout Shift.

3. FRONTEND RENDERER & VISUAL EDITOR INTEGRATION
- Implement a renderer component that parses `content_json` into responsive Tailwind blocks (Hero, Features, Form, Testimonials, CTA).
- Embed the open-source Puck editor (`@measuredco/puck`) on `/admin/edit/[id]` allowing marketers to drag, drop, and edit component props.
- Save configuration back to the PostgreSQL database.

4. FORM HANDLING & ANALYTICS
- Expose API route `/api/submit` to process POST submissions from embedded forms.
- Store submission data and fire background webhooks to external endpoints (Zapier/Klaviyo).
- Track view/conversion events via lightweight pixel route `/api/event` with non-blocking fetch calls.

5. OUT OF SCOPE & FAILURE HANDLING
- Exclude in-app collaboration comments and enterprise SSO.
- Handle missing query parameters gracefully by falling back to default DynamicRule values.
- Ensure non-existent slugs return standard 404 pages with zero middleware crashes.
