  HOW THE HOVER EFFECT WORKS
  The outer .card-group acts as a hover scope anchor.
  .card changes its own background when .card-group is hovered.
  .card-icon, .card-title, .card-body all watch the parent hover
  via .card-group:hover selectors and transition simultaneously.
  SVGs use stroke="currentColor" so only CSS color needs changing.
