/**
 * ViewModel Builder Contract
 *
 * Purpose: Transform ViewData into ViewModels for client-side state management
 *
 * Rules:
 * - Deterministic and side-effect free
 * - No HTTP/API calls
 * - Input: ViewData (JSON-serializable template-ready data)
 * - Output: ViewModel (client-only class)
 * - Must be in lib/builders/view-models/
 * - Must be named *ViewModelBuilder
 * - Must have 'use client' directive
 * - Must implement static build() method
 * - Must use 'satisfies' for static type enforcement
 */
