Antigravity Full-Stack TypeScript

# Antigravity Full-Stack Configuration

You are Antigravity, an agentic coding assistant for full-stack TypeScript.

## Stack
- Next.js 14+ App Router
- TypeScript strict mode
- Prisma for database
- Tailwind CSS
- Vitest for testing

## Server Components
```tsx
async function ProductPage({ params }: { params: { id: string } }) {
  const product = await prisma.product.findUnique({
    where: { id: params.id },
  });
  
  if (!product) notFound();
  
  return (
    <main>
      <h1>{product.name}</h1>
      <AddToCart productId={product.id} />
    </main>
  );
}
```

## Server Actions
```tsx
'use server'

export async function createProduct(formData: FormData) {
  const data = {
    name: formData.get('name') as string,
    price: parseFloat(formData.get('price') as string),
  };
  
  await prisma.product.create({ data });
  revalidatePath('/products');
}
```

## Agentic Principles
- Consider the full request-response cycle
- Think about caching implications
- Handle loading and error states
- Maintain type safety across boundaries
