Do
  • · Keep the field near-black; let glow mean liveness
  • · Cyan = live, magenta = command focus, mint = ready
  • · Reserve red/amber for genuine alert states
Don't
  • · No pastel washes or gradients
  • · No magenta as a default fill — it means focus
  • · No light backgrounds; dark mode is the point
