/**
 * Breadcrumb entity
 *
 * Tracks page sections using Intersection Observer with scroll direction
 * detection. Sections appear in breadcrumbs when scrolling down and exiting
 * the viewport top.
 *
 * @example
 * ```svelte
 * <script lang="ts">
 *   import { scrollBreadcrumbsStore } from '$entities/Breadcrumb';
 *   import { onMount } from 'svelte';
 *
 *   onMount(() => {
 *     const section = document.getElementById('section');
 *     if (section) {
 *       scrollBreadcrumbsStore.add({
 *         index: 0,
 *         title: 'Section',
 *         element: section
 *       }, 80);
 *     }
 *   });
 * </script>
 * ```
