   Set     aria-expanded and aria-hidden accordingly.
   Close   all other open panels on open (one at a time).
   Close   on outside click / Escape key.
   Update  .pf-active-count text + hidden attr when filters change.

/*
 * Variable defaults live on :root, not .pf-wrapper. [partner_feed_bind]
 * (the full-custom-design shortcode) only ever outputs an invisible,
 * zero-size marker div — the actual visible pills/cards live in the
 * designer's own Cornerstone markup elsewhere on the page, often as
 * siblings of that marker rather than descendants of it. A .pf-wrapper-
 * scoped variable never reaches them since CSS custom properties only
 * cascade to descendants. :root guarantees every element on the page can
 * see these regardless of where Cornerstone's design places things.
 * Partner_Feed_Shortcode::print_color_style() overrides the same
 * variables at :root when the admin has customized colors.
