   Velorex Music — hero carousel
   Used by: index.html (homepage only)

   One full-bleed banner that auto-switches between a brand slide (who Velorex
   is + the Categories / All Products calls to action) and a handful of
   featured-product slides carrying short details.

   Layout note — slides are GRID-STACKED, not absolutely positioned. Every
   slide occupies `grid-area: slide`, so the banner's height is the tallest
   slide's height and stays fixed as slides change. Absolute positioning would
   have needed a hard-coded height, which is how a carousel ends up either
   clipping a long product title or leaving a band of dead space on phones.
   This costs nothing: inactive slides are `visibility: hidden`, which also
   takes them out of the tab order, so no `inert`/tabindex bookkeeping is
   needed to stop a keyboard user tabbing into an invisible slide.

   Only the brand slide is in index.html. Product slides are injected by
   src/js/storefront/hero.js from the product cache. That split is deliberate:
   a crawler that never runs JavaScript still gets the full brand slide, the
   <h1> and the category links, exactly as it did before this file existed.
