   QUANTUM EXPERT HUD  (core/expert-hud.js)

   Lutfi's "Quantum Dawn Expert Stages" design. Its measurements are for a
   1918-pixel-wide screen; every size here is the design's own number times
   --s, which expert-hud.js sets from the play area (1 at 1600 px and wider,
   never under 0.62). A phone, or a window under 430 px tall, gets the
   compact layout at the end. --accent is the stage's colour.

   It sits over the canvas (z 3), under the banners, the touch pads and the
   sheets, and takes no clicks or taps.
