/**
 * Frappe Desk Theme - Custom CSS Styling
 * 
 * This stylesheet provides comprehensive theming support for Frappe Desk through CSS custom properties.
 * It covers login page customization, navigation styling, form elements, tables, widgets, and responsive design.
 * 
 * The theme system works by:
 * 1. JavaScript sets CSS custom properties (--variable-name) based on theme configuration
 * 2. CSS rules use these variables with var() function for dynamic styling
 * 3. Fallback values ensure functionality when theme data is unavailable
