 * @returns DemoExperience instance with control methods
 *
 * @throws {Error} If container element is not found

 * ```typescript
 * // Create and start demo with defaults
 * const demo = createDemoExperience('container', {
 *   customerName: 'Jane Smith',
 *   customerEmail: 'jane@acme.com',
 *   onStart: () => console.log('Demo started'),
 *   onHandoff: () => console.log('Handoff to presentation'),
 *   onEnd: () => console.log('Demo ended')
 * });
 *
 * await demo.start();
