I’ll engage with the editorialised title (which will probably be changed soon), “HTML is a native image format, hear me out”:

  data:image/svg+xml,
  <svg xmlns="http://www.w3.org/2000/svg">
    <foreignObject width="100%25" height="100%25">
      <div xmlns="http://www.w3.org/1999/xhtml">
        Behold!
      </div>
    </foreignObject>
  </svg>
