/* 023 Rush Hour — opaque, high-contrast HUD: ink on paper, hard borders, solid offset shadows. No gradients, no blur.
   v0.6 layout: one 8px grid (--u), one edge margin (--m) on top of the safe-area insets, four zones:
   top-left status (+ fines under it) · top-right group #tr (bill, car, mute, author mark) · bottom-left stick · bottom-right thumb cluster
   with the instrument strip (speed + propellant) sitting on the jet buttons. Floating things: 3px ink border + 4px hard shadow;
   inner gauges 2px. Purple only for the throttle, gauge fills, the stick knob and airborne jets. */
