 * A dark, low-chroma shell so the beams are the brightest thing on screen.
 * Everything in here is deliberately quiet: the canvas is the interface, and
 * the chrome exists to stay out of its way.
 *
 * Layout is a full-viewport stage with the HUD floating over it. Every control
 * for a piece lives on the bench itself, so the only chrome is the HUD and the
 * tray -- and the renderer measures both and fits the stage around them. On a
 * portrait phone the HUD packs into two rows and the stage turns sideways; on
 * a landscape phone the tray becomes a rail down the right-hand edge.
