import { ThemeProvider } from '@/components/theme-provider'
import { Sidebar } from '@/components/layout/sidebar'
import { Header } from '@/components/layout/header'

export default function RootLayout({
  children,
}: {
  children: React.ReactNode
}) {
  return (
    <html lang="en">
      <body>
        <ThemeProvider>
          <div className="flex h-screen">
            <Sidebar />
            <main className="flex-1 flex flex-col">
              <Header />
              <div className="flex-1 p-6">{children}</div>
            </main>
          </div>
        </ThemeProvider>
      </body>
    </html>
  )
}

// components/layout/sidebar.tsx
import { NavItem } from '@/components/nav-item'

@tailwind utilities;

@layer base {
  :root {
    --background: 0 0% 100%;
    --foreground: 222.2 84% 4.9%;
    --primary: 221.2 83.2% 53.3%;
    --secondary: 210 40% 98%;
    --accent: 210 40% 96%;
    --destructive: 0 84.2% 60.2%;
  }
  
  .dark {
    --background: 222.2 84% 4.9%;
    --foreground: 210 40% 98%;
    --primary: 217.2 91.2% 59.8%;
    --secondary: 217.2 32.6% 17.5%;
    --accent: 217.2 32.6% 17.5%;
    --destructive: 0 62.8% 30.6%;
  }
}

// tailwind.config.js
module.exports = {
  content: ['./app/**/*.{js,ts,jsx,tsx}'],
  theme: {
    extend: {
      colors: {
        border: 'hsl(var(--border))',
        background: 'hsl(var(--background))',
        foreground: 'hsl(var(--foreground))',
        primary: 'hsl(var(--primary))',
        secondary: 'hsl(var(--secondary))',
      }
    }
  },
  plugins: [require('@tailwindcss/typography')]
}
```

### Responsive Features

import { ButtonHTMLAttributes, forwardRef } from 'react'

interface ButtonProps extends ButtonHTMLAttributes<HTMLButtonElement> {
  variant?: 'default' | 'destructive' | 'outline' | 'secondary'
  size?: 'default' | 'sm' | 'lg'
}

const Button = forwardRef<HTMLButtonElement, ButtonProps>(
  ({ className, variant = 'default', size = 'default', ...props }, ref) => {
    return (
      <button
        className={cn(
          'inline-flex items-center justify-center rounded-md font-medium',
          'focus-visible:outline-none focus-visible:ring-2',
          'disabled:pointer-events-none disabled:opacity-50',
          {
            'bg-primary text-primary-foreground hover:bg-primary/90': variant === 'default',
            'bg-destructive text-destructive-foreground hover:bg-destructive/90': variant === 'destructive',
            'border border-input hover:bg-accent': variant === 'outline',
            'bg-secondary text-secondary-foreground hover:bg-secondary/80': variant === 'secondary',
          },
          {
            'h-10 px-4 py-2': size === 'default',
            'h-9 rounded-md px-3': size === 'sm',
            'h-11 rounded-md px-8': size === 'lg',
          },
          className
        )}
        ref={ref}
        {...props}
      />
    )
  }
)
```
