Starts from the current visual reference and project constraints.

Build a ui component named Accordion in React/Next.js.
Goal: recreate the same overall UI and behavior as the Accordion reference from a component gallery.
What it needs to communicate: Expandable accordion component with single-item expansion.

Project constraints:
- Use Next.js 16.2.6 with the App Router, React 19, TypeScript strict mode, and Tailwind CSS v4.
- Do not create a tailwind.config.js file. Use Tailwind v4 utilities and CSS variables where design tokens are needed.
- If you are implementing this inside the same project, use the Prompt font via next/font/google. If not, use the closest equivalent typeface.
- Return production-ready code with imports, responsive behavior, keyboard accessibility, and polished empty, hover, focus, active, and disabled states where relevant.
- Match the reference closely: color palette, spacing scale, border radius, shadows, icon scale, typography hierarchy, and motion timing.

Component-specific expectations:
- Keep the API concise and reusable.
- Make visual states feel polished and consistent across variants and sizes.
- Existing documented dependencies: lucide-react
- No explicit color literals were found in the examples. Match the live reference and the project accent color when appropriate.

Props to support:
- items: FAQItem[] — required — Array of accordion items with question and answer
- category: "general" | "account" — Optional category filter

Reference usage patterns:
- Basic Accordion

```tsx
<Accordion 
  items={[
    {
      question: "What is Next.js?",
      answer: "Next.js is a React framework...",
      category: "general"
    }
  ]} 
/>
```

Feature expectations:
- Single-item expansion (radio-style)
- Animated chevron rotation
- Optional category filtering
- First item open by default
- Client-side interactivity

Output requirements:
- Return complete code, not pseudocode.
- Include all necessary imports and helper types.
- Keep the implementation accessible, responsive, and visually finished.
- Match the reference for color, size, shape, typography, spacing, and interaction states as closely as possible.
- If multiple files are needed, organize them cleanly and explain the file structure briefly.

Tweak only product-specific copy or data after the first generation pass.
