+Description: This script processes JSON translation files for localization checks. It compares translation files in a branch with
+a reference file to ensure consistency. The script performs two main checks:
+1. Verifies that the number of translation keys in the translation files matches the reference file.
+2. Ensures that all keys in the translation files are present in the reference file and vice versa.
+
+The script also provides functionality to update the translation files to match the reference file by adding missing keys and
+adjusting the format.
+
+Usage:
+    python check_language_json.py --reference-file <path_to_reference_file> --branch <branch_name> [--actor <actor_name>] [--files <list_of_changed_files>]

+            ### Description of Changes
+
+            This Pull Request was automatically generated to synchronize updates to translation files and documentation for the **V2 branch**. Below are the details of the changes made:
+
+            #### **1. Synchronization of Translation Files**
+            - Updated translation files (`frontend/public/locales/*/translation.json`) to reflect changes in the reference file `en-GB/translation.json`.
+            - Ensured consistency and synchronization across all supported language files.
+            - Highlighted any missing or incomplete translations.
+
+            #### **2. Update README.md**
+            - Generated the translation progress table in `README.md`.
+            - Added a summary of the current translation status for all supported languages.
+            - Included up-to-date statistics on translation coverage.
+
+            #### **Why these changes are necessary**
+            - Keeps translation files aligned with the latest reference updates.
+            - Ensures the documentation reflects the current translation progress.

+# Stirling-PDF Unified Container
+
+Single Docker container that can run as **frontend + backend**, **frontend only**, or **backend only** using the `MODE` environment variable.
+
+## Quick Start
+
+### MODE=BOTH (Default)
+Single container with both frontend and backend on port 8080:
+
+```bash
+docker run -p 8080:8080 \
+  -e MODE=BOTH \
+  stirlingtools/stirling-pdf:unified
+```
+
+Access at: `http://localhost:8080`
+
+### MODE=FRONTEND
+Frontend only, connecting to separate backend:
+
+```bash
+docker run -p 8080:8080 \
+  -e MODE=FRONTEND \
+  -e VITE_API_BASE_URL=http://backend:8080 \
+  stirlingtools/stirling-pdf:unified
+```
+
+### MODE=BACKEND
+Backend API only:
+
+```bash
+docker run -p 8080:8080 \
+  -e MODE=BACKEND \
+  stirlingtools/stirling-pdf:unified
+```
+
+Access API at: `http://localhost:8080/api`
+Swagger UI at: `http://localhost:8080/swagger-ui/index.html`

+
+## Docker Compose Examples
+
+### Example 1: All-in-One (MODE=BOTH)
+
+**File:** `docker/compose/docker-compose-unified-both.yml`
+
+```yaml
+services:
+  stirling-pdf:
+    image: stirlingtools/stirling-pdf:unified
+    ports:
+      - "8080:8080"
+    volumes:
+      - ./data:/usr/share/tessdata:rw
+      - ./config:/configs:rw
+    environment:
+      MODE: BOTH
+    restart: unless-stopped
+```
+
+### Example 2: Separate Frontend & Backend
+
+**File:** `docker/compose/docker-compose-unified-frontend.yml`
+
+```yaml
+services:
+  backend:
+    image: stirlingtools/stirling-pdf:unified
+    ports:
+      - "8081:8080"
+    environment:
+      MODE: BACKEND
+    volumes:
+      - ./data:/usr/share/tessdata:rw
+      - ./config:/configs:rw
+
+  frontend:
+    image: stirlingtools/stirling-pdf:unified
+    ports:
+      - "8080:8080"
+    environment:
+      MODE: FRONTEND
+      VITE_API_BASE_URL: http://backend:8080
+    depends_on:
+      - backend
+```
+
+### Example 3: Backend API Only
+
+**File:** `docker/compose/docker-compose-unified-backend.yml`
+
+```yaml
+services:
+  stirling-pdf-api:
+    image: stirlingtools/stirling-pdf:unified
+    ports:
+      - "8080:8080"
+    environment:
+      MODE: BACKEND
+    volumes:
+      - ./data:/usr/share/tessdata:rw
+      - ./config:/configs:rw
+    restart: unless-stopped
+```
+
+---
+
+## Building the Image
+
+```bash
+# From repository root
+docker build -t stirlingtools/stirling-pdf:unified -f docker/Dockerfile.unified .
+```
+
+### Build Arguments
+
+| Argument | Description |
+|----------|-------------|
+| `VERSION_TAG` | Version tag for the image |
+
+Example:
+```bash
+docker build \
+  --build-arg VERSION_TAG=v1.0.0 \
+  -t stirlingtools/stirling-pdf:unified \
+  -f docker/Dockerfile.unified .
+```
+
+---
+
+## Use Cases
+
+### 1. Simple Deployment (MODE=BOTH)
+- **Best for:** Personal use, small teams, simple deployments
+- **Pros:** Single container, easy setup, minimal configuration
+- **Cons:** Frontend and backend scale together
+
+### 2. Scaled Frontend (MODE=FRONTEND + BACKEND)
+- **Best for:** High traffic, need to scale frontend independently
+- **Pros:** Scale frontend containers separately, CDN-friendly
+- **Example:**
+  ```yaml
+  services:
+    backend:
+      image: stirlingtools/stirling-pdf:unified
+      environment:
+        MODE: BACKEND
+      deploy:
+        replicas: 1
+
+    frontend:
+      image: stirlingtools/stirling-pdf:unified
+      environment:
+        MODE: FRONTEND
+        VITE_API_BASE_URL: http://backend:8080
+      deploy:
+        replicas: 5  # Scale frontend independently
+  ```
+
+### 3. API-Only (MODE=BACKEND)
+- **Best for:** Headless deployments, custom frontends, API integrations
+- **Pros:** Minimal resources, no nginx overhead
+- **Example:** Use with external frontend or API consumers
+
+### 4. Multi-Backend Setup
+- **Best for:** Load balancing, high availability
+- **Example:**
+  ```yaml
+  services:
+    backend-1:
+      image: stirlingtools/stirling-pdf:unified
+      environment:
+        MODE: BACKEND
+
+    backend-2:
+      image: stirlingtools/stirling-pdf:unified
+      environment:
+        MODE: BACKEND
+
+    frontend:
+      image: stirlingtools/stirling-pdf:unified
+      environment:
+        MODE: FRONTEND
+        VITE_API_BASE_URL: http://load-balancer:8080
+  ```
+
+---
+
+## Port Configuration
+
+All modes use **port 8080** by default:
+
+- **MODE=BOTH**: Nginx listens on 8080, proxies to backend on internal 8081
+- **MODE=FRONTEND**: Nginx listens on 8080
+- **MODE=BACKEND**: Spring Boot listens on 8080
+
+**Expose port 8080** in all configurations:
+```yaml
+ports:
+  - "8080:8080"
+```
+
+---
+
+## Health Checks
+
+### MODE=BOTH and MODE=BACKEND
+```yaml
+healthcheck:
+  test: ["CMD-SHELL", "curl -f http://localhost:8080/api/v1/info/status || exit 1"]
+  interval: 30s
+  timeout: 10s
+  retries: 3
+```
+
+### MODE=FRONTEND
+```yaml
+healthcheck:
+  test: ["CMD-SHELL", "curl -f http://localhost:8080/ || exit 1"]
+  interval: 30s
+  timeout: 10s
+  retries: 3
+```
+
+---
+
+## Troubleshooting
+
+### Check logs
+```bash
+docker logs stirling-pdf-container
+```
+
+Look for the startup banner:
+```
+===================================
+Stirling-PDF Unified Container
+MODE: BOTH
+===================================
+```
+
+### Invalid MODE error
+```
+ERROR: Invalid MODE 'XYZ'. Must be BOTH, FRONTEND, or BACKEND
+```
+**Fix:** Set `MODE` to one of the three valid values.
+
+### Frontend can't connect to backend (MODE=FRONTEND)
+**Check:**
+1. `VITE_API_BASE_URL` points to correct backend URL
+2. Backend container is running and accessible
+3. Network connectivity between containers
+
+### Backend not starting (MODE=BOTH or BACKEND)
+**Check:**
+1. Sufficient memory allocated (4GB recommended)
+2. Java heap size (`JAVA_CUSTOM_OPTS`)
+3. Volume permissions for `/tmp/stirling-pdf`
+
+---
+
+## Migration Guide
+
+### From Separate Containers → MODE=BOTH
+
+**Before:**
+```yaml
+services:
+  frontend:
+    image: stirlingtools/stirling-pdf:frontend
+    ports: ["80:80"]
+
+  backend:
+    image: stirlingtools/stirling-pdf:backend
+    ports: ["8080:8080"]
+```
+
+**After:**
+```yaml
+services:
+  stirling-pdf:
+    image: stirlingtools/stirling-pdf:unified
+    ports: ["8080:8080"]
+    environment:
+      MODE: BOTH
+```
+
+### From Legacy → MODE=BACKEND
+```yaml
+services:
+  stirling-pdf:
+    image: stirlingtools/stirling-pdf:latest
+    ports: ["8080:8080"]
+```
+
+**Becomes:**
+```yaml
+services:
+  stirling-pdf:
+    image: stirlingtools/stirling-pdf:unified
+    ports: ["8080:8080"]
+    environment:
+      MODE: BACKEND
+```
+
+---
+
+## Performance Tuning
+
+### MODE=BOTH
+```yaml
+environment:
+  JAVA_CUSTOM_OPTS: "-Xmx4g -XX:MaxRAMPercentage=75"
+  BACKEND_INTERNAL_PORT: 8081
+deploy:
+  resources:
+    limits:
+      memory: 4G
+    reservations:
+      memory: 2G
+```
+
+### MODE=FRONTEND (Lightweight)
+```yaml
+deploy:
+  resources:
+    limits:
+      memory: 512M
+    reservations:
+      memory: 256M
+```
+
+### MODE=BACKEND (Heavy Processing)
+```yaml
+environment:
+  JAVA_CUSTOM_OPTS: "-Xmx8g"
+deploy:
+  resources:
+    limits:
+      memory: 10G
+    reservations:
+      memory: 4G
+```
+
+---
+
+## Security Considerations
+
+1. **MODE=BOTH**: Backend not exposed externally (runs on internal port)
+2. **MODE=BACKEND**: API exposed directly - consider API authentication
+3. **MODE=FRONTEND**: Only serves static files - minimal attack surface
+
+Enable security features:
+```yaml
+environment:
+  DOCKER_ENABLE_SECURITY: "true"
+  SECURITY_ENABLELOGIN: "true"
+```
