/* Knight's Tour Foundation — site styles
   WCAG 2.2 AAA: 18px+ body, 44px+ targets, visible focus.
   Motion: only when someone acts (a click, a tap or a key), only line drawing and fading,
   and only under prefers-reduced-motion: no-preference (see "Tap-triggered motion" at the end).
   Every element rests in its finished drawing, so pages look complete with no motion.
   All sizes are in rem so the A / A+ / A++ buttons (100 / 125 / 150%) truly reflow.
   Layout breakpoints are container queries in rem, so a larger text size
   also moves the page to a narrower layout (columns stack, nothing scrolls sideways). */
