/**
 * Accordion Components
 * 
 * Project accordion for organizing estimates, jobs, and invoices.
 * Uses jQuery slideToggle for smooth animations with localStorage state persistence.
 * 
 * CRITICAL: Uses .expanded class + jQuery slideDown/slideUp for animations.
 * CSS display property is managed by JavaScript, not static CSS.

 * @package Silva_Customer_Portal
