/* The walkable arcade — page framing.
 * The stage fills the viewport under the fixed site banner. In it: the
 * room's canvas (internal pixels, scaled up by a whole number with hard
 * edges), the HUD canvas exactly over it, and the machine layer, which is
 * hidden until you step up to play and then shows the machine's own screen
 * over the room. The blurb lives below the fold.
