  /* ---- THE CHEVRON RULE (DESIGN.md "Chevron rule") -----------------------
     A plain bar of one thickness token with THREE chevrons SUBTRACTED from it,
     one near the start, one about a third along, one near the end, exactly like
     the original wand. The chevron is kadabra-first-edition-chevron.svg, sized
     `auto 100%` (or `100% auto` when vertical) so 28:64 is never stretched: the
     notch width follows the bar thickness. The wand SVG itself is never used. */
