/* =============================================================================
   Velorex Music — catalogue empty state
   Used by: #products-grid and #preowned-grid (catalogEmptyHtml() in
            src/js/storefront/pages.js) and the server-rendered empty listing
            in seo-render.php (velorex_catalog_empty_html()).

   Two situations share this block and must never share a message:
     "filtered"  — the shelf has stock, the shopper's filters excluded all of
                   it. Offers Adjust Filters + Clear All.
     "unstocked" — nothing is listed here at all. Saying "matching your current
                   filters" to someone who has not touched a filter reads as a
                   broken page, so this one says the shelf is empty instead.
