> Reduce duplication with story templates and shared args, and extend Storybook with parameters and global configuration.

## Story composition

Reduce duplication by sharing args between stories and composing stories from smaller pieces. This keeps stories maintainable.

## Template-based stories

Create reusable story templates.

```tsx
import type { Meta, StoryObj } from '@storybook/react';
import { Button } from './Button';

const meta = { component: Button, title: 'Components/Button' } satisfies Meta<typeof Button>;
export default meta;
type Story = StoryObj<typeof meta>;

// Shared args keep stories DRY
const base = { size: 'medium' } as const;

export const Primary: Story = { args: { ...base, variant: 'primary', children: 'Primary' } };
export const Secondary: Story = { args: { ...base, variant: 'secondary', children: 'Secondary' } };
```

## Custom parameters and hooks

Extend Storybook with custom parameters and hooks for specialized testing and documentation needs.

## Build-time optimization

Optimize Storybook build times by configuring webpack, using dynamic imports, and lazy-loading heavy addons.
