In terms of technical capabilities, what does Lexicon Design primarily offer?

Lexicon Design primarily offers a framework for developing rules and patterns, which plays a crucial role in ensuring consistency and coherence in user interface design across various applications. This framework encompasses guidelines for typography, spacing, colors, and components, all aimed at creating a unified experience for users. By establishing these design principles, Lexicon helps developers and designers understand how to implement visual styles effectively, ensuring that their work aligns with the overall Liferay ecosystem.

The framework is particularly beneficial as it allows for the systematic application of design standards across different projects, facilitating collaboration among teams and enhancing usability. This approach goes beyond merely providing visual styles or aesthetics; it revolves around the consistent application of design methodologies that enhance the user experience and interface functionality.

The other options, while related to design and coding, do not capture the essence of what Lexicon Design contributes. For instance, a set of visual styles alone would lack the comprehensive structure needed for cohesive design across applications. A coding language for new developers would not encompass the design-focused nature of Lexicon, and a library for external integration would detract from the core focus on user interface design principles that Lexicon is intended to provide.
