/*
 * trainitnow-child — Catalog filter bar
 *
 * Styles the `[tin_catalog_filters]` shortcode (see functions.php). Moved out
 * of woocommerce.css section [11] when the bar was redesigned: the old layout
 * was one flex row holding the search box and every dropdown, so each new
 * filterable attribute made the row longer, the boxes narrower and their
 * wrapping less predictable. This version stacks three fixed rows instead —
 * active-filter pills, the search row, and a collapsible even grid of
 * dropdowns — so the bar's height and rhythm no longer depend on how many
 * attributes a given site filters on.
 *
 * Panel visibility: `display: none` here, `display: grid` under `.is-expanded`
 * (toggled by js/catalog-filters.js), and forced open by an inline <noscript>
 * override in the shortcode. Collapsing is display-only — hidden <select>s
 * still submit their values, so a collapsed panel never silently drops a
 * filter.
