/* ==========================================================================
   SHARED WIDGET POPUP COMPONENT

   JS-positioned fixed popup with hover/touch activation. Used by the vector
   widget, portfolio heatmap, and info tooltips.

   Usage:
     1. Add class `has-popup` to the trigger element
     2. Inside the trigger, place a .widget-popup element with a direction modifier:
          .widget-popup--top    (popup appears above the trigger)
          .widget-popup--bottom (popup appears below the trigger)
          .widget-popup--left   (popup appears to the left of the trigger)
          .widget-popup--right  (popup appears to the right of the trigger)
     3. Add .widget-popup--compact for small inline tooltips (e.g. info icons)
     4. Popup shows on :hover or when the trigger has class .active (touch/tap)
     5. JS in app.js positions the popup as position:fixed on mouseenter so it
        always renders on top, even inside overflow:hidden containers.
