Contribution guide

1. Create a feature branch — never push directly to main.
2. Keep changes focused; avoid unrelated refactors.
3. Run npm run lint, npm run typecheck, npm run test, and npm run build before opening a pull request.
4. Never commit .env files, keys, or tokens.
5. Do not edit the shared UI library in src/components/ui/.

Documentation lives in docs-site/docs/ as Markdown/MDX.
