Core

In plain words

Core is a front-end feature kit designed for creating real, functional user interfaces. It addresses common problems with traditional UI kits by offering consistent styling and usable app components without the usual limitations. The kit is intended for designers and developers who need to move beyond template-based design to deploy functional products. Core combines design and development capabilities in a single tool.
