/**
 * Structra Utility Classes
 * ========================
 *
 * This file provides utility classes for common styling needs.
 * These utilities follow a consistent naming convention and can be
 * composed to build complex layouts without writing custom CSS.
 *
 * Naming Convention:
 * - .structra-{property}-{value}
 * - .structra-{property}-{breakpoint}-{value} (responsive)
 *
 * Breakpoints:
 * - sm: 640px
 * - md: 768px
 * - lg: 1024px
 * - xl: 1280px
