PRs and further features/optimizations are welcome.

I’d like to add a brief contribution guide so new contributors can get started quickly.

Proposed content

1. Fork the repository and create a feature branch.
2. Make focused changes with clear commit messages.
3. Test locally before opening a PR.
4. Open a PR with:
   • What changed
   • Why it changed
   • Screenshots (if UI changes)
5. Keep PRs small and link related issues.
