Contributing

We welcome contributions that improve clarity, correctness or performance. Our conventions:

  • Open an issue before large changes so we can align on design.
  • Keep PRs small and focused with tests for behaviour changes.
  • Follow the existing TypeScript and formatting (Prettier) config.
  • Add a short note on why the change matters.
