  <title>SVG Path and Text Regression Showcase</title>
  <desc>Each shape is drawn twice: a pale fill from a verbose path and a dark
        outline from the compact equivalent that path optimizers emit. The two
        forms describe the same geometry, so the dark outline must trace the
        pale shape exactly. The text blocks check anchoring, white space
        handling, style inheritance and multi chunk layout.</desc>
