**Kit UI** is a high-performance, aesthetically pleasing toolkit for developers and designers. It consolidates essential creative tools—from advanced color manipulation to ASCII art generation—into a single, unified workspace.

Built with **Next.js 16**, **React 19**, and **Tailwind CSS 4**, Kit UI delivers a lightning-fast, glassmorphic experience with a focus on precision and accessibility.

## 🚀 The Toolkit

Kit UI is divided into five core specialized applications:

### 🎨 [Color](./app/(app)/color) — Professional Color Toolkit
A comprehensive suite for color theory, manipulation, and accessibility.
- **Color Playground**: Interactive HSL/RGB/HEX manipulation with real-time analysis.
- **Accessibility Suite**: WCAG 2.1 Contrast Checker and a real-time Colorblindness Simulator.
- **Generative Tools**: Harmony generator (Analogous, Triadic, etc.), Palette Generator, and Gradient Architect.
- **Batch Processing**: Perform mass color operations and exports.
- **WASM Powered**: Utilizes `@valknarthing/pastel-wasm` for high-performance color calculations.

### 📐 [Units](./app/(app)/units) — Smart Unit Converter
A powerful, intuitive converter that understands the way you work.
- **187+ Units**: Supporting 23 categories including Length, Mass, Temperature, Force, and more.
- **Smart Search**: Quickly find units via a fuzzy-search command palette.
- **Visual Comparison**: Dynamic chart views for comparing scale across different units.
- **Favorites & History**: Save your most-used conversions for instant access.

### ✍️ [ASCII](./app/(app)/ascii) — ASCII Art Generator
Retro-inspired text banners for terminals and documentation.
- **373 Fonts**: From classic `Standard` to complex 3D and cursive styles.
- **Real-time Preview**: See your ASCII art transform as you type.
- **Multi-Export**: Copy as raw text, download `.txt` files, or export as `.png` images.

### 🎬 [Media](./app/(app)/media) — Browser-Based File Converter
Privacy-first, local-only media conversion powered by WebAssembly.
- **Video & Audio**: Transcode between MP4, WebM, MP3, WAV, and more using FFmpeg.
- **Image Processing**: Convert and resize PNG, JPG, WebP, and SVG via ImageMagick.
- **Zero Server Uploads**: All processing happens locally in your browser for maximum privacy.
- **Advanced Options**: Fine-tune bitrates, codecs, resolutions, and quality presets.

### 🌐 [Favicon](./app/(app)/favicon) — Favicon & PWA Generator
Complete asset generation for modern web presence.
- **Complete Icon Set**: Generates standard favicons, Apple Touch icons, and Android Chrome icons.
- **PWA Manifest**: Automatically generates a standards-compliant `site.webmanifest`.
- **HTML Snippets**: Copy-paste ready `<head>` tags for easy integration.
- **Privacy-First**: Powered by ImageMagick WASM—no server-side processing.

## 🛠️ Development & Deployment

### Prerequisites
- **Node.js**: 20.x or higher
- **pnpm**: 9.x or higher

### Local Development
```bash
# Clone and install
pnpm install

# Start development server with Turbopack
pnpm dev
```

### Production Build
```bash
# Build for static export
pnpm build

# The output will be in the /out directory
```

### Docker Deployment
```bash
# Build locally
docker build -t kit-ui .

# Run with Nginx
docker run -p 80:80 kit-ui
```

## 📈 Performance & Optimization

- **Static Site Generation (SSG)**: Entire toolkit is exported as static HTML/JS for sub-second load times.
- **Client-Side WASM**: Complex processing (FFmpeg, ImageMagick, Color) is offloaded to WebAssembly for native-level performance without server latency.
- **CSS-First Configuration**: Leveraging Tailwind 4's native CSS variables for zero-runtime styling overhead.
- **Automatic CI/CD**: GitHub Actions pipeline for multi-architecture Docker builds.
