Contributing

Thank you for contributing to html.

1. Open an issue before substantial behavior or architecture changes.
2. Keep changes focused and preserve the package boundaries described in AGENTS.md.
3. Use Go 1.26.3 or newer and avoid new dependencies unless they are necessary.
4. Add package-local tests for behavior changes.
5. Run just check and git diff --check before submitting a pull request.

For rendered UI changes, also run just qa-browser and include representative screenshots or generated HTML. Never include secrets, private source documents, or machine-specific paths in fixtures or reports.
