/**
 * Finesser Accounts - Global Styles
 * ==================================
 * 
 * This file contains global CSS utilities and overrides for the Finesser Accounts platform.
 * Most styling is done with Tailwind CSS classes, but some global styles are needed for:
 * - CSS custom properties (for dynamic theming)
 * - Scrollbar styling
 * - Animation keyframes
 * - Focus states
 * - Form element resets
