/* Palette, type, geometry — ported from villain and rotated to blue.
   Villain's red (#e5645a, HSL ~7° / 71% / 63%) is a warm coral, not a pure
   red; the blue below is the same character rotated to ~210° so the whole
   product still reads as a sibling of villain rather than a stock template
   dropped onto a new hue.

   --danger stays a genuine red so real errors don't disappear into the
