   Pixel rule: no rounded panels, no soft shadows; depth comes from inset
   bevels and hard offset shadows. Motion is transform/opacity apart from the
   drawer height and the sparkline draw, and is off under prefers-reduced-motion.
   Jersey 15 has one weight, so faux bold is disabled to keep its digits crisp. */
