Build a full-stack e-commerce marketing automation and transactional email engine using Next.js (App Router), PostgreSQL (Prisma ORM), Tailwind CSS, and Resend API.

CORE SYSTEM ARCHITECTURE:
1. DATA MODEL & SCHEMA:
   - Contact: id, email, phone, firstName, lastName, attributes (JSONB), status (subscribed, unsubscribed, bounced), createdAt.
   - List: id, name, description, createdAt.
   - Event: id, contactId, eventName (e.g., 'cart_updated', 'order_completed'), payload (JSONB), timestamp.
   - Campaign: id, name, subject, preheader, bodyHtml, status (draft, scheduled, sending, sent), sentCount, openCount, clickCount.
   - Workflow: id, name, triggerType, triggerCondition (JSONB), steps (JSONB array), active (boolean).

2. TRACKING & INGESTION API:
   - POST /api/v1/track: Ingests e-commerce events (cart updates, checkouts). UPSERT Contact by email. Store Event in DB. Trigger background evaluation of active Workflows for this contact.
   - GET /api/v1/tracking/open/[messageId]: Returns a 1x1 transparent GIF. Increments campaign/workflow open counters and logs activity event.
   - GET /api/v1/tracking/click/[messageId]?url=...: Decodes destination, records click event, redirects to target URL.

3. WORKFLOW AUTOMATION ENGINE:
   - Event-driven runner (Node.js background process or Next.js background route) that evaluates step trees:
     * TRIGGER: Event matched (e.g., eventName == 'cart_updated' AND payload.cartValue > 50).
     * DELAY: Wait X hours (store state in DB queue table with scheduledAt).
     * CONDITION: If contact hasn't placed order (check if 'order_completed' event exists after trigger time), proceed to SEND_EMAIL.
     * ACTION: Render React Email template injected with contact attributes & cart payload, send via Resend SDK.

4. CAMPAIGN BUILDER UI:
   - WYSIWYG/Markdown email editor allowing dynamic variables like {{contact.firstName}} or {{event.cartItems}}.
   - Segment builder with UI filters: Attribute rules (e.g., spent > 100), Event history rules (e.g., interacted in last 30 days).
   - Campaign dashboard showing deliverability metrics: Sent, Opens, Clicks, Unsubscribes, Bounces.

OUT OF SCOPE:
- Native drag-and-drop HTML builder (use Markdown or code editor with React Email preview).
- WhatsApp gateway integrations (SMS/Email only).
- Multi-tenant billing and subscription tiers.

FAILURE MODES TO HANDLE:
- Webhook duplicate processing: Ensure idempotency key checking on incoming e-commerce webhooks.
- Unsubscribe compliance: Automatically append RFC-8058 List-Unsubscribe headers and handle instant opt-out requests without authentication.
