   FOOTER ACCORDION (Каталог / Клієнтам)
   Desktop: identical to the original design — header/icon/toggle markup
   is simply invisible and inert, columns are always fully expanded.
   Mobile: real collapsible accordion (JS toggle, see core-bridge.js) —
   the brand column and Контакти stay always visible since they're short
   and essential; only the two link-heavy columns collapse, so mobile
   doesn't get a wall of footer text on load.
