This library is a class-based architectural framework for developing accessible Vue 3 UI components and modular design systems. Its primary function is to abstract complex component logic—specifically ARIA accessibility management, reactive state synchronization, and DOM interaction patterns—into reusable "Include" classes and component constructors. It provides a robust engine for input validation, pattern-based masking (text, number, currency, date), and sophisticated layout transitions via motion-transform and axis-based animation systems.

An AI should study this library’s API when implementing or extending high-level UI components that require strict ARIA compliance, complex focus trapping (TabIndexInclude), or advanced input handling like autosizing textareas and formatted masks. It is indispensable for managing multi-state UI elements such as modals, snackbars, and nested menus where consistency in state synchronization (ModelInclude) and event-driven data flows is required. The library is also relevant for developers creating Vite/Rollup plugins to automate component imports or transform SCSS into mixin-based style modifications.

The framework is tightly integrated with the Vue 3 ecosystem, utilizing ShallowRef, ComputedRef, and VNode for performance-optimized rendering logic. It relies on a functional utility layer for low-level data processing and includes a dedicated Vite plugin to handle design-system-specific SCSS transformations and component resolution. The architecture follows a strict separation of concerns, where component configuration is defined via "constructors" while core logic is encapsulated in "Include" classes, enabling highly consistent behavior across diverse UI elements.
