generate a clamp for a range of page indexes

computed.js

const clampedPaginatedIndex = computed(() => {
  const page = parseInt(response.products?.page ?? 1);
  const lastPage = response.products?.last_page ?? 1;

  const clampRange = Math.min(5, lastPage);
  const offset = Math.max(0, Math.min(page - Math.ceil(clampRange / 2), lastPage - clampRange));

  return Array.from({ length: clampRange }, (_, index) => offset + index + 1);
});
