   CAROUSEL — reusable component (music + merch)
   Two fixes learned from l-imperatrice.cool's .c-slider:
   1. The wrapper is `position: relative; overflow: hidden;` —
      this clips anything that tries to blow out past its box,
      the same way .c-slider does.
   2. `min-width: 0` on the wrapper itself. It's a CSS Grid item,
      and grid items default to min-width: auto — meaning the
      box refuses to shrink below its content's natural width
      even with overflow set on a child. That let the whole
      component (buttons included, since they're positioned
      relative to it) balloon past the viewport. min-width: 0
      is the actual fix; overflow: hidden is the safety net.
