The Shadows setting controls the box-shadow applied globally to every card-style component on the page: Info Cards, Speaker cards, Sponsor logo tiles, FAQ panels, and any section using a card layout.
💡Shadow and border work well together at low intensities: try Very subtle shadow + 1px border for a clean card look, or Elevated shadow + no border for a floating effect. Avoid using both at high values simultaneously.
