/* ---------------------------------------------------------------------------
   GT Motors — Night HUD
   Implements "Turn 2 / Night HUD variant" from the Claude Design canvas
   (boards 2a–2f): night navy, neon edge, bracketed HUD panels, mono readouts.

   Visually hands off from the stand's own screen. The design notes it trades
   some direct-sunlight legibility for that, so the brightness here is pushed as
   far as the palette allows: #F2F7FF on #050C1A is ~17:1.
