  description: |
    **Complete REST API specification for KiviCare healthcare management system**

    Esta é a especificação completa da Care API baseada na análise do código fonte v1.0.0.

    ## 🔐 Autenticação
    Esta API usa **JWT (JSON Web Tokens)** para autenticação:
    1. **Login:** `POST /auth/login` com username/password
    2. **Token:** Incluir no header `Authorization: Bearer <token>`
    3. **Refresh:** Tokens expiram em 24h, use `/auth/refresh`
    4. **Rate Limiting:** 10 tentativas/hora para login, 1000 requests/hora para API

    ## 📊 Estrutura de Resposta Padronizada
    **Sucesso (2xx):**
    ```json
    {
      "success": true,
      "data": {...},
      "message": "Operation completed successfully",
      "timestamp": "2025-09-14T10:30:00Z"
    }
    ```

    **Erro (4xx/5xx):**
    ```json
    {
      "success": false,
      "message": "Error description",
      "error_code": "VALIDATION_ERROR",
      "timestamp": "2025-09-14T10:30:00Z"
    }
    ```
