🚀 Add automated deployment script with detailed options and instructions in documentation

code/websites/pokedex.online/DEPLOYMENT.md

@@ -6,7 +6,69 @@ Pokedex.Online uses a multi-container Docker setup with:
 - **Frontend**: Nginx serving built Vue.js application
 - **Backend**: Node.js Express server (OAuth proxy + Gamemaster API)
 
-## Quick Deploy
+## Automated Deployment (Recommended)
+
+Use `deploy.sh` for a complete, automated deployment with built-in safety checks.
+
+### Basic Usage
+
+```bash
+# Deploy to internal network
+./deploy.sh --target internal
+
+# Deploy to external (requires Cloudflare tunnel)
+./deploy.sh --target external --port 8080 --backend-port 3000
+
+# Dry run (preview without deploying)
+./deploy.sh --dry-run --target internal
+```
+
+### Options
+
+- `--target <internal|external>` - Deployment target (default: internal)
+- `--port <number>` - Frontend HTTP port (default: 8080)
+- `--ssl-port <number>` - Frontend HTTPS port (optional)
+- `--backend-port <number>` - Backend port (default: 3000)
+- `--skip-tests` - Skip test execution
+- `--skip-build` - Skip build step (use existing dist/)
+- `--no-backup` - Skip backup creation
+- `--dry-run` - Preview without deploying
+
+### What deploy.sh Does
+
+The deployment script automates the entire process:
+
+1. **Prerequisites Check** - Verifies Node.js, npm, and dependencies
+2. **Environment Validation** - Checks for server/.env configuration
+3. **Test Suite** - Runs frontend and backend tests
+4. **Build Process** - Builds and verifies the application
+5. **Backup Creation** - Creates timestamped backup (keeps last 5)
+6. **Deployment** - Transfers files and starts containers
+7. **Verification** - Health checks both services
+8. **Summary** - Reports deployment URLs and next steps
+
+### Examples
+
+```bash
+# Standard internal deployment
+./deploy.sh --target internal
+
+# External deployment with custom ports
+./deploy.sh --target external --port 8080 --ssl-port 8443
+
+# Quick deploy (skip tests, use existing build)
+./deploy.sh --skip-tests --skip-build
+
+# Development iteration (no backup needed)
+./deploy.sh --no-backup --target internal
+
+# Check what would happen
+./deploy.sh --dry-run
+```
+
+## Manual Deployment
+
+### Quick Deploy
 
 ```bash
 # Deploy to internal network (10.0.0.81)
