/* The Train page. One thing to look at first (your house), then the games in a clear order: a big one, two medium ones, then plain rows for the rest, then practice and the map.
   The house is a live 3D preview (house.js, loaded by hub.js when it scrolls into view); until it has drawn, and if 3D cannot run, the stage shows your character. */
