/* ==========================================================================
   TOOLTIP
   ==========================================================================
   CSS-only tooltip via data-tip attribute — instant, unlike the native
   title attribute's ~1s delay. Usage:

       <button data-tip="Click to copy">…</button>
       <button data-tip="Undo" data-tip-pos="bottom">…</button>

   Shows on hover and keyboard focus. Top-centered by default;
   data-tip-pos="bottom" flips it below the element. data-tip is visual
   only — elements without visible text still need an aria-label.
