/* Get Less Chaos: A Place for Everything. Components.
   Every component is a PIECE (sits on the board, lifts in the hand, presses home), a POCKET (a cut with green
   showing), or a piece in its pocket. Hover lifts a piece to show its slot; press puts it home; focus seats it and
   draws the cut line. Needs tokens.css + base.css. Motion here is CSS-only; motion.js adds the choreographed moves. */
