/**
 * BIOMER Catalog Styles (v2.8.8)
 *
 * ИЗМЕНЕНИЯ v2.8.8 (08.10.2026): плашка «Все отрасли …» под тулбаром каталога
 *                    (.ind-quickfilter → .ind-filter) — перенос блока отраслей
 *                    с главной; клик фильтрует сетку по отрасли через AJAX.
 * ИЗМЕНЕНИЯ v2.8.7 (этап 3 аудита): CTA «Получить КП» в Hero каталога
 *                    (.hero-cta → /contacts/) + липкая нижняя панель на моб.
 *                    ≤767px (.mobile-cta-bar, включается JS-ом, когда Hero-кнопка
 *                    ушла из вида; body.biomer-cta-visible даёт отступ снизу).
 * ИЗМЕНЕНИЯ v2.8.0: аккордеон сайдбара — hover для десктопа, плавная анимация раскрытия,
 *                    курсор-указатель на группах (поведение старого сайта / Smart Menus).
 * ИЗМЕНЕНИЯ v2.7.0: иерархические группы категорий (parent → children) в сайдбаре
 * ИЗМЕНЕНИЯ v2.6.0: sidebar filters → category links
 * 
 * Вынесено из header-shop.php для:
 * - Единой системы стилей
 * - Корректного кэширования браузером
 * - Возможности редактирования через FTP
 * 
 * Используется на: /production/, /product-category/*, /library/

/* ===== ПЛАШКА ОТРАСЛЕЙ ПОД ТУЛБАРОМ (v2.8.8) =====
   Тот же вид, что у блока отраслей на главной, но:
   - счётчики на кнопках = количество ТОВАРОВ в отрасли (сумма по подотраслям),
     чтобы совпадали с «Найдено» после клика;
   - кнопки шлют AJAX-фильтр (catalog.js → biomer_filter, параметр ind),
     а не переключают карточки, как на главной. */
