/* =====================================================================
 * MasnoonHub Express - Faceted shop filters
 * Desktop sticky sidebar card + active-filter chips + mobile top
 * filter/sort bar + bottom sheet. Ported from faceted-filters-mockup.html
 * (Saif-approved), scoped under .mh-catalog, mhf- prefixed so nothing
 * collides with the existing catalog CSS. Companion JS: shop-filters.js.
 *
 * Number font: Noto Serif Bengali for all DISPLAY numerals (prices, counts,
 * badges, slider, chip values). Body/labels stay Hind Siliguri. The font is
 * enqueued by inc/mh-shop-filters.php (handle mh-sf-fonts).
 *
 * Breakpoint 960px matches woo-catalog.css (where .desk-side hides): at/below
 * it the sidebar is gone and the mobile bar + sheet take over.
