/* ============================================================
   --- WIDA language-level toggle: tooltip variant show/hide ---

   When the library has multiple WIDA variants for a term (e.g.
   tooltip :: sheltered AND tooltip :: entering), the builder emits
   both as siblings inside .term-multi. Only ONE should ever be
   visible at a time; the inactive one is hidden via display:none.

   These rules live HERE in components-terms.css (not site.css)
   because they need to override the .term:hover/focus .term-tip
   un-hide rules above. Tied specificity (both 0,3,1) means cascade
   order decides — same-file later-defined rules win. !important is
   added belt-and-suspenders so the hide stays even if a future
   refactor moves these rules elsewhere.

   The visible-DOM variants are siblings inside .term-multi:
     <span class="term term-multi">word
       <span class="term-tip" data-wida-variant="L3">L3 text...</span>
       <span class="term-tip" data-wida-variant="L1">L1 text...</span>
     </span>

   In default L3 mode, hide L1.
   In L1 mode (:root[data-wida="L1"]), show L1 and hide L3.
