/* ==========================================================================
   Shared search + filter unit

   Single source of truth for the .etb-filter-unit component (search row,
   filter buttons, dropdown panels, active chips). Loaded on any listing page
   that carries the `.etb-listing` class on its wrapper — currently the Videos
   landing and the Free Tools archive landing. Edit the filter's look here and
   it changes on every page at once.

   Extracted verbatim from videos-landing.css (which held the only copy) so the
   two pages could stop drifting apart. The rules use bare selectors and lean
   on general palette tokens (--etb-orange, --color-text-*, --color-border-*)
   that each landing already defines on its own wrapper; only the tokens unique
   to the filter live here, on `.etb-listing`.
