```js
// demo-button.stories.js

import { html } from 'lit-html';

import './demo-button';

//👇 We create a “template” of how args map to rendering
const Template = ({ primary, label }) =>
  html`<demo-button ?primary=${primary} .label=${label}></demo-button>`;

//👇 Each story then reuses that template
export const Primary = Template.bind({});

Primary.args = {
  primary: true,
  label: 'Primary',
};
