Deploy static site / Deploy to GitHub Pages (push) Has been cancelled
Deploy static site / Deploy via Docker to hatch.surf (push) Has been cancelled
Merge GitHub main into Gitea repo (allow unrelated histories)
Resolved conflicts by taking GitHub versions for:
- .dockerignore, .gitignore, Dockerfile, README.md, docker-compose.yml

Kept deploy.sh updated to:
- Pull from GitHub (primary source)
- Push to Gitea (push-mirror)
- Build from site/ directory (GitHub structure)
