What do Themes allow developers to maintain in Liferay?

Themes in Liferay are designed to enable developers to create a unified and visually appealing user interface across different devices. This is essential for ensuring that users have a consistent experience, whether they are accessing the platform from a desktop, tablet, or smartphone. By applying themes, developers can control the look and feel of websites, including layout, color schemes, typography, and other visual elements, facilitating a cohesive branding and design strategy across various platforms.

The other choices do not specifically relate to the primary function of themes in Liferay. Database integrity is maintained through data management and database configuration practices, security protocols are enforced through system configurations and code practices rather than themes, and server performance is influenced by application architecture and optimization strategies rather than the visual design elements that themes address.
