```ts
// Button.stories.ts

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

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: '📚📕📈🤓',};
