/*
 * Bootstrap 3 Compatibility Styles for Bootstrap 4.6.2
 * 
 * Purpose:
 * This file provides compatibility fixes for the Bootstrap 3.3.5 to 4.6.2 upgrade.
 * It addresses layout and styling differences caused by Bootstrap 4's shift from 
 * float-based to flexbox-based grid system.
 * 
 * Issues Fixed:
 * - Dropdown padding, hover behavior, and caret display
 * - Footer alignment (centering)
 * - Button alignment in forms (float-based layout restoration)
 * - Sign-in page background height
 * - Session expiration modal display and centering
 * - HR element spacing
 * 
 * Usage:
 * Load this file AFTER bootstrap.min.css in all pages using Bootstrap.
 * The CSS uses !important declarations to override Bootstrap 4 defaults.
 * 
 * Maintenance:
 * When adding new fixes, reference Bootstrap 3.3.5 behavior from:
 * /bootstrap/css/bootstrap-3.3.5-backup.min.css
