/* ===========================================
   Themed tooltips (TASK-291)
   Replaces the browser's default (unstyled) title="" popups. Any element with a
   `data-tooltip="…"` attribute shows a token-styled bubble on hover / keyboard focus.
   Pure CSS, no JS. Token-only. Use INSTEAD of native `title` for help text.

     <button data-tooltip="Lift this user's mute.">Unmute</button>

   Notes:
   - The bubble is absolutely positioned relative to the element; an ancestor with
     non-visible overflow can clip it (same caveat as any CSS tooltip). For toolbars
     mid-content this is fine.
   - `data-tooltip-pos="bottom"` flips it below the element (for things near the top).
