/*
 * ==============================================================================
 * FormStudio - Premium Form Builder
 * Main Custom Stylesheet (assets/css/style.css)
 * ==============================================================================
 * WHAT DOES THIS FILE DO?
 * While the application predominantly uses Tailwind CSS utility classes for layout
 * and styling, this file handles advanced, pseudo-class, and custom visual 
 * properties that are either not natively supported by standard Tailwind classes 
 * or are better managed globally. 
 * 
 * Contents:
 * - Custom scrollbars
 * - Drag and Drop visual indicators
 * - Complex CSS animations (fade-in, slide-up, scale)
 * - Specific overrides for form elements (checkboxes, radio buttons)
