  AxisQuest — Light Theme (Modernist)
  Binding for all surfaces. One accent (red), spent sparingly. Structure is
  communicated with 2px solid ink rules, never tinted panels. Zero corner
  radius everywhere - --radius/--radius-sm stay at 0 so every existing
  border-radius: var(--radius) reference collapses automatically; a few
  hardcoded circle/pill shapes (999px, 50%) are flattened explicitly below.
  Game-state color mapping lives inline next to the relevant component.
