/* Bootstrap (loaded only on this page, for the grid + carousels) sets a
   base `a:hover, a:focus { text-decoration: underline; }` with no scoping,
   so it leaks onto the nav, sidebar and every other link. Our own hover
   rules only ever touch `color`, never `text-decoration`, so nothing else
   cancels it out. Same specificity as Bootstrap's rule (0,1,1); this file
   loads after bootstrap.min.css so it wins the tie. */
