-## Split Deployment Configuration
-
-Stirling PDF supports separating frontend and backend for better scalability and deployment flexibility.
-
-### Deployment Modes
-
-Configure deployment mode via the `MODE` environment variable:
-
-| Mode | Description | Use Case |
-|------|-------------|----------|
-| `BOTH` | Frontend + Backend (default) | Single container deployment |
-| `BACKEND` | Backend only | API service, split deployment |
-| `FRONTEND` | Frontend only | Static frontend serving |
-
-### Frontend URL Configuration
-
-When using split deployment or load balancers, configure the frontend URL for generating links:
-
-```yaml
-system:
-  frontendUrl: 'https://pdf.example.com'
-```
-
-**Environment Variable:**
-```bash
-SYSTEM_FRONTENDURL=https://pdf.example.com
-```
-
-**Use Cases:**
-- Email invite links point to correct frontend
-- Download links reference proper URL
-- API responses include frontend URLs
-
-### CORS Configuration
-
-When frontend and backend are on different domains, enable CORS:
-
-```yaml
-system:
-  corsAllowedOrigins:
-    - 'https://pdf.example.com'
-    - 'https://pdf-staging.example.com'
-```
-
-**Environment Variable:**
-```bash
-SYSTEM_CORSALLOWEDORIGINS=https://pdf.example.com,https://pdf-staging.example.com
-```
-
-**Security Best Practices:**
-- Only specify trusted origins
-- Never use wildcard (`*`) in production
-- Always use HTTPS in production
-- Keep list minimal

-## 🔀 Split Deployment Architecture
-
-**NEW:** Deploy frontend and backend separately for better scalability.
-
-### What's New
-
-Three deployment modes:
-
-#### 1. Unified Mode (Default)
-Single container with frontend + backend together.
-
-```bash
-docker run -d \
-  -p 8080:8080 \
-  stirlingtools/stirling-pdf:latest
-```
-
-#### 2. Split Mode
-Frontend and backend in separate containers.
-
-**Backend:**
-```bash
-docker run -d \
-  -e MODE=BACKEND \
-  -p 8081:8080 \
-  stirlingtools/stirling-pdf:latest
-```
-
-**Frontend:**
-```bash
-docker run -d \
-  -e MODE=FRONTEND \
-  -e VITE_API_BASE_URL=http://backend:8080 \
-  -p 8080:8080 \
-  stirlingtools/stirling-pdf:latest
-```
-
-#### 3. Backend-Only Mode
-Use as API-only service.
-
-```bash
-docker run -d \
-  -e MODE=BACKEND \
-  -p 8080:8080 \
-  stirlingtools/stirling-pdf:latest
-```
-
-### Benefits
-
-- **Independent Scaling:** Scale frontend and backend separately
-- **CDN Integration:** Serve static frontend from CDN
-- **Development:** Work on frontend without running backend
-- **Security:** Separate concerns, different security zones

-### CORS Configuration
-
-New settings for split deployment:
-
-```yaml
-system:
