+## Publicação automática no npmjs (GitHub Actions)
+
+Foi adicionado workflow em `.github/workflows/publish-npm.yml`.
+
+### Como configurar
+
+1. No GitHub do repositório, configure o secret:
+   - `NPM_TOKEN`: token de automação do npmjs com permissão de publish.
+2. Faça commit com versão atualizada no `package.json`.
+3. Crie e envie uma tag semântica:
+
+```bash
+git tag v1.1.1
+git push origin v1.1.1
+```
+
+Ao subir a tag `v*.*.*`, o workflow executa `npm ci`, `npm run build` e `npm publish`.
