/* Gooey Nav Indicator — original.
   A horizontal nav where a liquid pill indicator travels between links. The
   pill and a trailing "drop" live inside a goo layer that runs an inline SVG
   filter (feGaussianBlur → feColorMatrix), so the two shapes merge and the
   indicator stretches with surface tension as it moves — then re-forms on the
   hovered / focused / active link.
   Every selector is scoped to .byq-gem--gooey-nav-01. */
