## ✨ Highlights

- **Premium SaaS UI:** Features a meticulously crafted dark mode aesthetic with custom grid backgrounds, radial gradients, and micro-interactions.
- **Custom Components:** Includes from-scratch Tailwind components like animated toggle switches and dynamic rollout progress bars without relying on heavy external UI libraries.
- **State-Driven Design:** The interface instantly reacts to feature toggles, graying out inactive elements and highlighting live features with vibrant indigo accents.
- **Responsive Layout:** A mobile-first approach with a collapsible sidebar and fluid grid cards that scale perfectly from phones to ultrawide monitors.

## 🧱 Project Structure

```text
src/
|-- main.tsx          # Application entry point
`-- app.tsx           # Main dashboard layout, mock data, and custom UI components
```

## 🛠️ Tech Stack

- Preact 10 with Vite 6
- Tailwind CSS 4 for utility-first styling
- `lucide-preact` for clean, scalable iconography

## 🚀 Local Development

```bash
npm install
npm run dev
```

Open `http://localhost:5173` to view the dashboard in your browser. The UI is currently populated with mock data for immediate layout testing.

## 🔌 Extension Notes & Nuances

- **NOTE: Backend Integration:** This project is designed as a frontend template. To make it functional, the `toggleFlag` function and the initial `flags` state inside `app.tsx` should be connected to a real API (e.g., using `fetch` to update a PostgreSQL database or a Redis store).
- **NOTE: CSS Grid Pattern:** The custom background grid is defined purely in CSS inside `src/index.css`. You can adjust the `background-size` or opacity to change the "density" of the engineering grid.

## 🧪 Build & Checks

```bash
npm run build
npm run preview
```
