+
+## NucleoDataCard.vue
+
+A flexible and centralized card component for displaying data entities.
+
+### Purpose
+
+The `NucleoDataCard` component provides a standardized way to display information in a card format. It's designed to be adaptable to various data types and styling requirements through props and slots. It supports a header (with optional avatar, title, and status), a body for displaying data fields and an optional observation section, and a footer with action buttons.
+
+### Props
+
+| Prop                | Type    | Default     | Description                                                                 |
+|---------------------|---------|-------------|-----------------------------------------------------------------------------|
+| `title`             | String  | _Required_  | The main title of the card, typically displayed in the header.              |
+| `status`            | String  | `''`        | A status string to be displayed as a badge in the header.                   |
+| `fields`            | Array   | `[]`        | An array of objects (`{ label: String, value: String }`) for data rows. Each object represents a piece of data to be displayed with a label and its value. |
+| `accentColor`       | String  | `'#808080'` | Hex color code for the card's top border.                                   |
+| `backgroundColor`   | String  | `'#FFFFFF'` | Hex color code for the card's background.                                   |
+| `avatarUrl`         | String  | `''`        | URL for an avatar image to be displayed in the header.                      |
+| `observation`       | String  | `''`        | A text string for an observation section displayed below the fields.        |
+| `showEditButton`    | Boolean | `true`      | Whether to display the default Edit button in the footer.                   |
+| `showDeleteButton`  | Boolean | `true`      | Whether to display the default Delete button in the footer.                 |
+
+*Note: `accentColor` and `backgroundColor` are applied using inline styles. The default status badge styling in the header slot might not work as expected with hex `accentColor` values for its default Tailwind classes; use the `header` slot for custom status styling if needed.*
+
+### Slots
+
+-   **`header`**: Allows custom content or layout for the card header. If used, it overrides the default header structure which includes the avatar, title, and status badge.
+-   **`body`**: Allows complete customization of the main card content area. If used, you are responsible for rendering the content that would normally go here, such as iterating through the `fields` prop and displaying the `observation` prop. The default content of this slot handles the rendering of `fields` and `observation`.
+-   **`footer`**: Allows custom content to be injected at the beginning of the card footer, before the `actions` slot and default Edit/Delete buttons.
+-   **`actions`**: Allows adding custom buttons or other interactive elements to the footer. These are rendered before the default Edit and Delete buttons if they are visible.
+
+### Events
+
+-   **`edit`**: Emitted with no payload when the default Edit button (if shown) is clicked.
+-   **`delete`**: Emitted with no payload when the default Delete button (if shown) is clicked.
+
