     - Unboxed open-canvas monumental Space Grotesk display typography
     - 92% Architectural Monochrome + 1 Surgical Signal Amber (#F59E0B) accent
     - Exposed 1px shared-seam matrices + '+' structural crosshairs
     - Linear/Rauno cursor-tracked radial border & surface spotlight (--mx, --my)
