/*
 * REFLEXIVITY CSS - MODULAR ARCHITECTURE
 * =====================================
 * 
 * This is the main CSS file that imports all modular components.
 * 
 * ARCHITECTURE:
 * - Base: Foundation styles (variables, reset, typography)
 * - Components: Reusable UI components (buttons, grids, navigation)
 * - Sections: Page-specific sections (hero, capabilities, footer)
 * - Utilities: Helper classes (responsive, animations)
