/**
 * AdminLTE Header & Menu UI/UX Update
 * UI/UX Pro Max: Minimalism & Swiss Style + Healthcare Color Palette
 *
 * Summary of AdminLTE UI Structure:
 * - Header (.main-header): Fixed top header with logo and navbar
 * - Logo (.logo): Left side logo area (255px width)
 * - Navbar (.navbar): Right side navigation with toggle button, page title, and user menu
 * - Sidebar (.main-sidebar): Left side navigation menu (255px width)
 * - Sidebar Menu (.sidebar-menu): Tree structure menu with icons and labels
 * - Menu Items: Single items and treeview items with submenus
 *
 * Design Principles Applied:
 * - Minimalism & Swiss Style: Clean, spacious, functional, high contrast
 * - Healthcare Color Palette: Calm blue primary, soft backgrounds
 * - Smooth Transitions: 200-250ms hover effects
 * - Proper Z-Index: z-50 for nav, z-40 for dropdowns
 * - Typography: Inter font family (consistent with app)
 */

/**
 * AdminLTE Header & Menu UI/UX Update
 * Uses shared variables from colors.css and spacing.css
 *
 * Note:
 * - Colors are imported from colors.css
 * - Spacing, radius, and transitions are imported from spacing.css
 * - Sidebar-specific colors are mapped to ocean blue theme

   `.sidebar-toggle:before { content: "\f0c9" }` (fa-bars) — independent of
   whatever icons we put inside. There's also a more specific
   `.main-header .sidebar-toggle::before` rule in the same vendor file, so a
