## Introduction
Varlet is a Vue 3 component library that follows Material Design specifications. It was originally built for mobile interfaces but has expanded to support desktop layouts, providing components for forms, navigation, feedback, and data display.

## What Varlet Does
- Provides 60+ Vue 3 components following Material Design 2 and 3 guidelines
- Supports both mobile-first and desktop-responsive layouts
- Offers on-demand component importing for optimized bundle sizes
- Includes dark mode with runtime theme switching via CSS variables
- Ships with internationalization support for 20+ languages

## Architecture Overview
Varlet components are built with the Vue 3 Composition API and TypeScript. The styling system uses CSS custom properties organized into design tokens for colors, spacing, and elevation. Components support on-demand loading through a Vite or Webpack plugin that rewrites imports to include only the CSS and JS for components actually used. A CLI tool helps scaffold projects and generate component documentation.

## Self-Hosting & Configuration
- Install from npm and register globally or import individual components
- Use the unplugin-vue-components plugin for automatic on-demand importing
- Customize the theme by overriding CSS variables on the `:root` selector
- Configure dark mode via the `StyleProvider` component or the `Themes.dark` utility
- Supports Vite, Webpack, and Nuxt build environments

## Key Features
- Material Design 3 support with dynamic color theming
- Touch gestures and mobile interactions built into relevant components
- On-demand tree shaking to minimize production bundle size
- CLI for project scaffolding and component documentation generation
- TypeScript type definitions for all components and APIs
