{{-- One item of an `<x-carousel>`: a slide of art — an `<img>`, which fills and crops to the
     item, or any element sized `size-full`.

         <x-carousel-item label="Lake Constance">
             <img src="{{ $photo->url }}" alt="Lake Constance at dusk" />
         </x-carousel-item>

     `label` lays a short line of text over the bottom of the art, on a scrim, pinned to the
     item's visible edge and fading out as the item narrows — Compose's carousel sample, which
     fades its label chip in once the mask is wide enough to hold it. The scrim is what M3 asks
     for under text on an image; the text itself is `inverse-on-surface`, a role a scheme and a
     contrast profile follow, rather than a literal white.

     A focusable `group` with `aria-roledescription="slide"`, named "n of m" by the carousel
     around it. M3 puts the tab stop on the item, not on the row: Tab reaches the first item, the
     arrow keys move between them and Space or Enter opens the focused one
     (docs/reference/m3/components-actions-communication-containment.md § Carousel →
     Accessibility). The item is laid out at the carousel's large size and masked:
     the surface inside is clipped by `--material-carousel-inset` from both sides with M3's
     extra-large corner (28px, CarouselDefaults' item shape) and moved by
     `--material-carousel-shift`, both written by resources/js/carousel.js. Without script the
     item shows unmasked, at its `item-width`. In a `full-screen` carousel it is none of that: the
     item fills the row, edge to edge, with no corner and no mask. Only inside `<x-carousel>`. --}}
