In the Atlas framework, where should partials be added to customize an app's design?

In the Atlas framework, partials should be added under the Web section to customize an app's design. Partials are reusable components or pieces of UI that can enhance the consistency and maintainability of the application's design. By placing partials in the Web section, developers can ensure that these components are integrated into the page structure correctly and can be utilized across different parts of the application.

This approach leverages the modular nature of web development, allowing for easier updates and modifications to the user interface without the need to duplicate code. Partials can encapsulate specific design elements or functionalities that are common across various pages, making it straightforward to implement design changes across the entire application.

The other options, such as Styles or Scripts, are more focused on styling and functionality rather than the structural arrangement of UI components. Designs as a choice might refer to overall design templates rather than the specific addition of reusable parts, making the Web section the most appropriate choice for managing partials in the Atlas framework.
