   Actually check index.css: --accent: 210 40% 96%
   The user sees a grey bar? Or is it styled differently? 
   Let's check SigFigCalculator.tsx: className="... border-l-accent ..."
   If accent is light grey, it might be subtle. Let's make it distinct or match exactly.
   Let's use a darker grey to be visible or keep it subtle as in preview.
   Actually, let's use the primary-ish color for "Operations" to make it pop if accent is too light.
   Or stick to the exact CSS var.
