- Updated Dockerfile base image: node:22-alpine → node:24-alpine
- Regenerated package-lock.json to sync with package.json Tailwind v4
- Docker build now completes successfully (npm ci no longer fails)
- Docker compose with .env.example runs without errors
- Application verified accessible and functional in Docker
- Instagram extraction pipeline tested successfully
