```js
// Button.stories.js

//👇 We create a “template” of how args map to rendering
const Template = (args) => ({
  Component: Button,
  props: args,
});

//👇 Each story then reuses that template
export const Primary = Template.bind({});
Primary.args = { background: '#ff0', label: 'Button' };

export const Secondary = Template.bind({});
Secondary.args = { ...Primary.args, label: '😄👍😍💯' };

export const Tertiary = Template.bind({});
Tertiary.args = { ...Primary.args, label: '📚📕📈🤓' };
