    <p>
      This page makes fine-tuning animations easier. Use the animation previewer
      at the bottom right to test the last-run animation at various speeds,
      scrub through manually, or play in reverse.
    </p>

    <p>
      Custom animations can be defined as a single, pure function. For example,
      <code>Custom1</code> uses only a few lines:
    </p>

    <code>
      <pre>

(targets, _x, _y, _count, entity) => ({
    targets,
    from: entity === 'module' ? Math.random() * 200 : 200,
    duration: 500,
    easing: 'cubic-bezier(1,1,0,.5)',
    web: {
        opacity: [0, 1],
        scale: [0.3, 1.13, 0.93, 1],
    },
});
    </pre
      >
    </code>

    <p>
      See <code>components/qr-code/animations.ts</code> to review the built-in
      presets. (Pull requests welcome!)
    </p>

    <p>
      Use the controls below to test any animations defined in the page source.
      Animations can independently control center icons, so the largest QR code
      below includes an example icon.
    </p>

    <small
      >Note, a memory leak will eventually slow down this page after many
      animation runs, but that doesn't matter if you're editing a custom
      animation in the source and regularly reloading.</small
    >

    <p>
      Animation:
      <select id="animationName">
        <option>FadeInTopDown</option>
        <option>FadeInCenterOut</option>

      The <code>squares</code> option renders modules as squares, but they can
      still be individually animated:
    </p>

    <qr-code

      squares="true"
      style="width: 150px; height: 150px; background-color: #fff"
      onclick="document.getElementById(this.id).animateQRCode(currentAnimation());"
    >
      <!-- should be ignored when squares === true -->
      <img src="assets/bch.svg" slot="icon" />
    </qr-code>

    <p>Scan test at small sizes:</p>
    <qr-code
      id="tiny"
      onclick="document.getElementById(this.id).animateQRCode(currentAnimation());"
      contents="bitcoincash:?r=https://bitjson.com/i/example-invoice-id"
