## Overview

LexUI is a reusable React design system for Next.js and Vite, with a CLI for adopting and checking its conventions. The principal workflow is for a developer to initialize a consumer project, then build an interface using LexUI foundations and component packages; charts and flow diagrams are optional capabilities. The SaaS demo shows how those pieces can support authentication, operational views, and design-system browsing. The README documents tokens and CLI capabilities beyond the sampled source, so those links reflect documentation; unsampled demo wiring is not inferred.

Main entry points: [`apps/demo-saas/app/(product)/layout.tsx`](https://github.com/washingtonalvesviana/lexui-design-system/blob/main/apps/demo-saas/app/(product)/layout.tsx) (SaaS demo shell), [`packages/react/src/index.ts`](https://github.com/washingtonalvesviana/lexui-design-system/blob/main/packages/react/src/index.ts) (React components), [`packages/cli/src/index.mjs`](https://github.com/washingtonalvesviana/lexui-design-system/blob/main/packages/cli/src/index.mjs) (LexUI CLI), [`apps/demo-saas/app/(product)/dashboard/page.tsx`](https://github.com/washingtonalvesviana/lexui-design-system/blob/main/apps/demo-saas/app/(product)/dashboard/page.tsx) (Metrics dashboard)
