## Description

Lona is a framework and set of utilities designed to synthesize centralized design definitions into cross-platform UI code, visual artifacts, and motion assets. It functions as a design system generator that converts a single set of specifications into native code for multiple operating systems, Sketch files, and other visual outputs.

The system includes a motion design renderer that integrates motion files and renders them into video files to maintain consistent animation experiences. It also features a design artifact exporter for generating localized screenshots and bulk image exports based on predefined design system definitions.

The project covers a broad range of design workflow capabilities, including design system management for components and styles, visual component prototyping through a graphical interface, and data-driven design previews to validate layout accuracy. It utilizes a headless engine and an intermediate representation model to process structural layout definitions independently of specific graphics libraries.
