/**
 * Reactive helper factories using Svelte 5 runes
 *
 * Provides composable state management patterns for common UI needs:
 * - Filter management with multi-selection
 * - Typography controls with bounds and stepping
 * - Virtual scrolling for large lists
 * - Debounced state for search inputs
 * - Entity stores with O(1) lookups
 * - Character-by-character font comparison
 * - Persistent localStorage-backed state
 * - Responsive breakpoint tracking
 * - 3D perspective animations
 *
 * @example
 * ```ts
 * import { createFilter, createVirtualizer, createTypographyControl } from '$shared/lib/helpers';
 *
 * const filter = createFilter({ properties: [...] });
 * const virtualizer = createVirtualizer(() => ({ count: 1000, estimateSize: () => 50 }));
 * const control = createTypographyControl({ value: 16, min: 12, max: 72, step: 1 });
 * ```
