/*
 * Design B: Collapsible Icon Rail Sidebar
 * Building Manager shell layout — icon rail with expand/collapse toggle
 *
 * Depends on builtair.css for brand tokens, typography,
 * Bootstrap overrides, cards, buttons, footer, etc.
 *
 * This file defines the shell chrome:
 *   - Icon rail sidebar (64px collapsed, 220px expanded)
 *   - Toggle button for expand/collapse
 *   - Flyout panel (admin sub-menu, collapsed state only)
 *   - Utility bar (top of main content)
 *   - Bottom tab bar (mobile)
 *   - Full-screen overlay nav (mobile)
 *   - Main content wrapper offsets
