/* v1.7.5 fix, take 2: the previous fix here was `[data-tooltip] {
   position: relative; }` moved to the top of the file so it would always
   LOSE a same-specificity cascade tie against any component's own
   position:fixed/absolute rule declared later. That's fragile -- it only
   holds as long as every future fixed/absolute component happens to be
   declared after this line, which is exactly the assumption that broke
   .guide-toggle in the first place. Scoping this to .io-toggle
   specifically -- the ONLY one of the 3 data-tooltip elements that is
   actually position:static and needs the assist -- removes the race
   entirely: .guide-toggle and .assistant-handle's own position:fixed
   rules are never touched by the tooltip system at all, regardless of
   file order. */
