/* ============================================
   EXPLANATION OF KEY CONCEPTS:
   ============================================
   
   COLOR SCHEME:
   - Blue (#007bff): Primary actions, selected items
   - Green (#28a745): Success, available, recommended
   - Orange/Yellow (#ff9800, #ffc107): Warnings, sub-optimal
   - Red (#dc3545): Errors, busy slots, conflicts
   - Gray (#6c757d): Secondary text, disabled states
   
   TRANSITIONS:
   - Most elements have 0.2s-0.3s transitions
   - This makes hover effects smooth
   - transform: translateY(-2px) = lifts element up
   - transform: scale(1.05) = makes element slightly bigger
   
   Z-INDEX LAYERS:
   - 10: Hovered time slots (above other slots)
   - 9998-9999: Modal overlay and content (in booking-system-init.js)
   - 10000: Help modal (above booking modal)
   
   FLEXBOX vs GRID:
   - Flexbox: Used for horizontal layouts, centering
   - Grid: Used for calendar (7 columns), booking flow (2 columns)
