 * styles/hud.css pins the HUD canvas to the largest centred 16:10 rectangle that
 * fits the viewport, because the HUD is authored at 320x200 and its gauges have
 * to stay circular. The 3D view is given the identical rectangle, so the two
 * layers line up exactly and the bottom paper strip sits flush with the bottom of
 * the picture.
 *
 * The pleasant consequence: Stage.resize() derives its buffer from the canvas
 * client size, so a 200-line target in a 16:10 frame comes out at literally
 * 320x200 — the resolution this whole look is built around.
