Read the docs and examples
Confirm the behavior is not already documented or demonstrated.
Contribution guide
Leave the project clearer than you found it.
Open a focused issue
Describe the use case, expected outcome, environment, and a minimal reproduction when reporting a defect.
Keep changes narrow
Update tests and documentation alongside a behavior change. Avoid unrelated formatting or refactors in the same pull request.
Respect browser security
Never add client-side secrets or assume frontend checks authorize a backend operation.
