### Description: - We need a Makefile to simplify local development, Docker workflows, and environment setup. Key targets include: - env – copy .env.example to .env. - start / start-full – dev server (lightweight / full). - build / serve – production build and serve. - Docker targets – docker-build, docker-run, docker-run-dev, docker-shell. - Code quality – lint, lint-fix, format, reinstall. ### Benefit: - Simplifies contributor setup, reduces CPU load, and standardizes Docker workflows. ### Additional Notes: - Use environment variables safely (GATSBY_DEFAULT_SITE_URL). - Ensure start skips heavy image processing to avoid overheating laptops.
