+
+## Project
+
+Kit UI is a static-export toolkit (Next.js 16, React 19, TypeScript strict) with five browser-based tools: Color, Units, ASCII, Media, and Favicon. All heavy processing runs client-side via WebAssembly. Deployed at kit.pivoine.art.
+
+## Commands
+
+```bash
+pnpm dev          # Dev server with Turbopack (localhost:3000)
+pnpm build        # Static export to /out
+pnpm lint         # ESLint (next/core-web-vitals)
+pnpm postinstall  # Copies WASM binaries to public/wasm/ (runs automatically on install)
+```
+
+There are no test suites. Use `pnpm build` to verify changes compile correctly.
+
+## Architecture
+
+### Routing (App Router)
+
+```
+app/
+├── page.tsx              # Landing page (dark mode forced)
+├── (app)/layout.tsx      # Wraps all tools with Providers + AppShell
+├── (app)/color/          # Color manipulation (@valknarthing/pastel-wasm)
+├── (app)/units/          # Unit converter (187+ units, 23 categories)
+├── (app)/ascii/          # ASCII art (373 figlet fonts)
+├── (app)/media/          # File converter (FFmpeg + ImageMagick WASM)
+└── (app)/favicon/        # Favicon/PWA asset generator
+```
+
+### Code Organization
+
+Each tool follows a mirrored structure across three directories:
+
+- **`app/(app)/{tool}/page.tsx`** — Route entry point
+- **`components/{tool}/`** — UI components for the tool
+- **`lib/{tool}/`** — Business logic, WASM wrappers, stores, and utilities
+- **`types/`** — Shared TypeScript definitions
+
+Shared UI primitives live in `components/ui/` (shadcn/ui, customized with glassmorphic styling). Layout shell in `components/layout/`.
+
+### State Management (three layers)
+
+1. **URL params** — Primary for shareable state (`useSearchParams` / `useRouter().push`)
+2. **React Query** — Async WASM computations with caching
+3. **Zustand** — Per-tool client stores in `lib/{tool}/`
+4. **localStorage** — Persistence for theme, favorites, history
+
+### WASM Integration
+
+WASM modules (FFmpeg, ImageMagick, pastel-wasm) are lazy-loaded on first use. Binaries live in `public/wasm/` and are copied there by the postinstall script — don't move them manually. WASM logic is browser-only; do not attempt to run it in Node.
+
+## Conventions
+
+- **`'use client'`** only where needed (WASM, browser APIs, interactive state). Default to RSC.
+- **Styling**: Tailwind CSS 4 with CSS-first config in `app/globals.css`. Use `cn()` from `lib/utils/cn.ts` for conditional classes. Use `@utility glass` for glassmorphic effects and gradient utilities (`gradient-purple-blue`, etc.).
+- **Icons**: Lucide React exclusively.
+- **Imports**: Use `@/` path alias (resolves to project root).
+- **Components**: shadcn/ui from `components/ui/` as building blocks.
+- **Logic/UI separation**: Business logic in `lib/`, UI in `components/`. Keep them separate.
+
+## Deployment
+
+Static export (`output: 'export'` in next.config.ts) served by Nginx via Docker. No Node.js runtime in production.
+
+```bash
+docker build -t kit-ui .
+docker run -p 80:80 kit-ui
+```
+
+## PWA
+
+Service worker at `public/sw.js` pre-caches core assets and WASM binaries. Manifest generated from `app/manifest.ts` (force-static). Cache version: `kit-ui-v1`.

+# GEMINI.md - Kit UI Context
+
+This file provides foundational context and instructions for Gemini CLI when working in the `kit-ui` workspace.
+
+## 🚀 Project Overview
+
+**Kit UI** is a high-performance, aesthetically pleasing toolkit built with **Next.js 16**, **React 19**, and **Tailwind CSS 4**. It provides five core specialized applications:
+
+1.  **Color**: Advanced color theory, manipulation, and accessibility suite powered by `@valknarthing/pastel-wasm`.
+2.  **Units**: Smart unit converter supporting 187+ units across 23 categories, including a custom `tempo` measure.
+3.  **ASCII**: ASCII Art generator with 373 fonts and multi-format export.
+4.  **Media**: Browser-based file converter using **FFmpeg** and **ImageMagick** via WebAssembly.
+5.  **Favicon**: Asset generator for web icons, PWA manifests, and HTML snippet headers.
+
+**PWA Capabilities**: The toolkit is a fully functional Progressive Web App with service worker integration for offline usage of WASM-based tools.
+
+## 🛠️ Tech Stack & Architecture
+
+- **Framework**: Next.js 16 (App Router, Static Export).
+- **Library**: React 19.
+- **Styling**: Tailwind CSS 4 (CSS-first configuration in `app/globals.css`).
+- **Animations**: Framer Motion 12.
+- **State Management**: Zustand & React Query.
+- **Performance**: Heavy logic (Color, Media) is offloaded to **WebAssembly (WASM)**.
+- **UI Components**: shadcn/ui (customized for a glassmorphic aesthetic).

+└── types/                # TypeScript definitions
+```
+
+## ⚙️ Development Workflows
+
+### Key Commands
+
+- **Development**: `pnpm dev` (Uses Next.js Turbopack).
+- **Build**: `pnpm build` (Generates a static export in `/out`).
+- **Lint**: `pnpm lint`.
+- **WASM Setup**: `pnpm postinstall` (Automatically copies WASM binaries to `public/wasm/`).
+
+### Coding Standards
+
+1.  **Tailwind 4**: Use the new CSS-first approach. Avoid `tailwind.config.js`. Define theme variables and utilities in `app/globals.css`.
+2.  **Glassmorphism**: Use the `@utility glass` for translucent components.
+3.  **WASM Orchestration**: Heavy processing should stay in `lib/[tool]/` and utilize WASM where possible. Refer to `lib/media/wasm/wasmLoader.ts` for pattern-loading FFmpeg/ImageMagick.
+4.  **Client-Side Only**: Since this is a static export toolkit that relies on browser APIs (WASM, File API), ensure components using these are marked with `'use client'`.
+5.  **Icons**: Exclusively use `lucide-react`.
+
+## 🧠 Strategic Instructions for Gemini
+
+- **Surgical Updates**: When modifying tools, ensure the logic remains in `lib/` and the UI in `components/`.
+- **WASM Handling**: Do not attempt to run WASM-dependent logic in the terminal/Node environment unless specifically configured. These tools are designed for the browser.
+- **Styling**: Adhere to the `glass` and gradient utilities (`gradient-purple-blue`, etc.) defined in `app/globals.css`.
+- **Component Consistency**: Use shadcn components from `components/ui/` as the building blocks for new features.
