        <h1>contrast-color-picker</h1>
        <p>Web component color picker with WCAG contrast guides. Drop-in replacement for <code>&lt;input type="color"&gt;</code> with visual contrast indicators.</p>

        <h2>Usage</h2>
        <p>Click swatch to open picker. Click reference area to change background. Plus signs = acceptable contrast.</p>
        <p><code>&lt;contrast-color-picker value="#3498db" reference="#ffffff"&gt;&lt;/contrast-color-picker&gt;</code></p>

        <div style="display: flex; gap: 2rem; justify-content: center; align-items: flex-start; flex-wrap: wrap;">
          <div style="flex: 1; min-width: 300px; text-align: center;">
            <h3>Basic</h3>
            <contrast-color-picker value="#3498db"></contrast-color-picker>
          </div>
          <div style="flex: 1; min-width: 300px; text-align: center;">
            <h3>With Reference Color</h3>
            <contrast-color-picker value="#ff5733" reference="#4411ee"></contrast-color-picker>
          </div>

        <h2>Form Integration</h2>
        <p>Works seamlessly in forms:</p>
        <form onsubmit="event.preventDefault(); alert('Form submitted with color: ' + document.getElementById('form-color').value)">
          <label>
            Theme Color: <contrast-color-picker
              id="form-color"
              name="themeColor"
              value="#00ff00"
              reference="#ffffff">
            </contrast-color-picker>
          </label>
          <button type="submit">Submit</button>
        </form>

        <h2>Smart Positioning</h2>
        <p>Native popover API handles positioning automatically:</p>
        <div style="display: flex; gap: 1rem; flex-wrap: wrap; justify-content: space-between;">
          <contrast-color-picker value="#ff0000" reference="#ffffff"></contrast-color-picker>
          <contrast-color-picker value="#00ff00" reference="#000000"></contrast-color-picker>
          <contrast-color-picker value="#0000ff" reference="#f0f0f0"></contrast-color-picker>
