Build and Push Docker Image to Gitea / build-and-push (push) Successful in 1m38s
- Re-enable output: 'standalone' in next.config.ts for Docker builds - Remove public directory copy from Dockerfile (not needed for this project) - Standalone mode works with force-dynamic routing to prevent SSR issues Fixes Gitea Actions build failure where .next/standalone was not found
