/* WorkBot Payroll UI System (Phase 6-7 Enhanced)
   - Pure CSS variable system (no hardcoded colors)
   - Bootstrap 5 CSS baseline with WorkBot customizations
   - Provides reusable layout + component primitives for payroll surfaces
   
   ARCHITECTURE:
   - Section 0: Global theme variables (aliases to theme.css)
   - Section 1: Micro-animations and transitions
   - Section 1b: Navigation and branding
   - Section 1c: Form headers and components (Phase 7)
   - Section 2: Typography scale
   - Section 3: Cards and surfaces
   - Section 4: Badges and status indicators
   - Section 5: Tables and key-value layouts
   - Section 6: Alerts and banners
   - Section 7: Sticky elements and shadows
   - Section 8: Micro-interactions (Phase 7)
   - Section 9: Form controls and buttons
   - Section 10: Responsive design (Phase 7)
   - Section 27: Dark mode helpers
   
   DESIGN SYSTEM:
   - Color variables: --primary, --text, --bg, --border (from theme.css)
   - Spacing scale: --space-xs (4px), --space-sm (8px), --space-md (16px), --space-lg (24px), --space-xl (32px)
   - Transitions: 0.2s ease (standard), 0.15s ease (quick), 0.6s ease (slow)
   - Shadows: --shadow-elevated, --shadow-sticky
   - No hardcoded hex colors (test_intelligence_polish_invariants enforces this)
