    | Page navigation. Pass a Laravel `paginator` (LengthAwarePaginator) and it
    | wires up the links automatically, or pass `currentPage` / `lastPage` plus a
    | `href` callback via the `links` slot for manual control.
    |
    | variant: full (numbered window) or simple (prev/next with "Page X of Y").
    | A CursorPaginator automatically renders as simple prev/next.
    |
    | Usage:
    |   <x-ui.pagination :paginator="$users" />
    |   <x-ui.pagination :current-page="3" :last-page="10" />
    |   <x-ui.pagination variant="simple" :current-page="3" :last-page="10" />
    |   <x-ui.pagination :paginator="$users->cursorPaginate(15)" />
