/* Mam's Block Puzzle: a wooden board and chunky wooden blocks, big buttons and big writing, for a phone held upright
   or an iPad on its side. As in Dadtris, the board and the pieces are drawn by three.js on the #view canvas laid over
   the page; #board-slot and the .tray-slot boxes only mark where (render/scene.js reads their positions). Each look
   is a body class setting the colours below (js/looks.js has the matching board and block colours). */
