/* mod_carcatalog_filter — "sitehome" layout.
   The actual visual design (icon-frame button) now lives in the
   component's shared media/css/carcatalog.css (.carcat-sh-*), reused
   as-is so this button stays visually identical to mod_carcatalog_tools'
   "sitehome" buttons, by construction rather than by two copies kept in
   sync by hand. This file is kept as the enqueue target for any future
   page-specific override that only applies on the site's main homepage. */
