/* "Molten core": cold silver at the edge, getting hotter toward the centre.
   The outer walls stay pure silver, the flow band warms, the petals glow and the centre is
   red-hot with a white-hot point. In the story each layer has its own heat; the hero mark,
   drawn as one piece, keeps silver lines with a red-hot heart.
