   The nav item is 41px tall inside an 84px header and the panel is offset a
   further 10px, leaving a measured 20px dead zone between them. Dragging the
   pointer down towards the panel crossed header space belonging to neither
   element, so mouseleave fired on .nav__item and the panel closed before it
   could be reached. This pseudo-element spans that gap. It belongs to the panel,
   which is a descendant of .nav__item, so hovering it keeps :hover on the item
   and never fires mouseleave. It is only hit-testable while the panel is open,
   because the closed panel is pointer-events: none.
   `bottom` resolves against the padding box, so the panel's 3px top border has
   to be added back or a 1px seam is left exactly on the item's bottom edge.
   Height covers the 10px open-state gap plus 2px of overlap. */
