守株待兔

The video is this document. The narration is the text of each Line, and every animation starts on a word of it, when that word is spoken.

    <Scene id="cover" duration={2.8}>
      <Part id="stage0"><Stage s={0} /></Part>
      <Part id="book" x={330} y={100} w={700} h={800}>{() => (
        <div style={{position: 'relative', width: 700, height: 800}}>
