   - make the column behave like the approved Daniel 2 statue visual
   - remove the nested stage conflict
   - center the artwork vertically and horizontally inside the art figure
   - keep background transparent
   - keep HTML/CSS marker numbers and connector lines independent from image
   - leave one small tuning area for live adjustment
